A Reluctant Rock


The Upland Footpath team returned to the fells at the start of April to commence this year's projects. This coincided nicely with a stretch of good weather.

Our first project of 2015 has been on the path up Tongue Gill to Grisedale Tarn, near to the village of Grasmere.
View up Tongue Gill during our commute one sunny April day
This path is on the Coast to Coast route devised by Alfred Wainright. This long distance route, of around 190 miles, goes between St Bees in Cumbria on the Irish Sea to Robin Hood's Bay on the Yorkshire Coast.  The Coast to Coast route is one of the most popular long distance routes in the UK. It is also well known worldwide and the number of international visitors we have met seems to reflect this.

The team were able to start this project immediately as rock we were using had been flown into position during last year's helicopter lifts. This rock was donated to "Fix the Fells" by a private land owner who last year completed a hydro-electric scheme on Tongue Gill. This surplus rock was a by-product of the excavations during construction. We always try to use rock that is local to an area for our work so this donation was gratefully received.

As a popular route lots of work has been carried out on the Tongue Gill path over the years to tackle the problem of erosion.  Path work is then monitored as new erosion can develop and previous work sometimes needs "fettling". This year's project involves a typical range of remedial work including drainage, stone "pitching" (both repairs and new) and landscaping work to stabilise erosion and remove side routes.

A memorable part of this project for the author of this blog led to the title "A Reluctant Rock".  Whilst working on a new section of stone pitching a suitable rock was identified. This rock was on the large side but was manageable and had several good faces making it an ideal step for walkers to plant their feet on as they follow the path.

Towards the end of the first day, as time was running out, a slightly rushed decision to move the rock into position was made. Unfortunately the rock dropped into the hole at an awkward angle and refused to be manoeuvred into the desired position.
The hole around the rock then had to be filled to leave it safe until the next time.
The "reluctant rock" at the end of the first day
On the return it proved very difficult to get the desired leverage on this rock with a metal bar and bedrock kept getting in the way. Lots of digging, levering and chipping away at the bedrock followed but still the rock remained largely uncooperative.

Lunchtime on the second day fast approaching & rock is in a "new" position... 

Determination and patience were needed plus a reluctance to be "beaten" by a rock and it was eventually coaxed into position by lunchtime (albeit a slightly later lunch than normal).

The saga of this rock did provide a talking point and possibly some amusement to passing walkers. Comments to a colleague working further down the path mentioned the size of the rock and one couple commented on their return journey that "He's still working with the same rock....".

After lengthy negotiations a compromise has been reached
This reluctant rock was used for part of a longer section of work. Some side route erosion was developing next to some bedrock between two sections of stone pitching.  This is because some walkers have a tendency to avoid bedrock.

To solve this we decided to add more stone pitching to join up the two current sections and to use landscaping techniques to stabilise and remove the side route. This can be seen from the before and after images below:
BEFORE: Side route erosion developing to the right of a bedrock section 

AFTER: New stone pitching section built & side route removed
At the time of writing this blog our time on Tongue Gill is nearly finished.  This is ahead of schedule largely due to the volunteer help we have had. 
We have several other projects this season including a return to Striding and Swirral Edges to continue work we have been doing there. We also have a project near the summit of Coniston Old Man where significant erosion problems have been developing.

Holiday in the Hills

This week the blog comes from the South Lakes Upland Ranger team.
A Holiday in the Hills probably sounds like a lovely idea, however it is worth noting that this holiday involved 5 days of Upland Footpath work. (Perhaps not everyone's idea of lovely.)
The first working day was a Sunday, the participants having arrived the day before and settled into the bunkhouse at High Wray.  As an introduction to footpath work we took the group on a "drain run". This involves checking an existing footpath route emptying the drains and clearing loose stone from any "stone pitched" sections of path.
The group, including one from Australia and one from Belgium, got stuck into this task and did a thorough job. Unfortunately it was quite a harsh introdution as the weather was not kind with wind and icy rain throughout the day. Although it was a good time to see how the drainage was working.

Grim introduction: A drain run on a cold wet & windy day
After a grim first day we wondered if everyone would return on the Monday as very occasionally participants make an early exit. We needn't have worried as everyone was back bright and early to meet us at the Three Shires Stone on the Wrynose Pass. The group also brought with them much nicer weather.
Early morning warm up by the Three Shires Stone
(Much nicer weather too)
The work for the next two days was on one of the team's main projects for the year, the footpath from Red Tarn to Crinkle Crags.  The group worked on a part where people were spreading out and a widening erosion scar was developing. The plan was to use landscaping techniques to remove any side routes and create a tighter more manageable path line.

Before: Path widening and erosion scar developing 
The landscaping approach used is sometime referred to as "hump & hollow". It involves stripping turf and re-shaping the ground next to the path into humps and hollows.  The idea is to make this area unattractive to walk on so that people don't want to spread out. Once we are happy that the shapes of the humps and hollows are fairly natural looking the turf that was stripped off is re-laid. In addition grass seed (specially mixed for the fells) is used on any bare patches so the landscaping will green over and blend into the fellside.

During: Group working to remove side routes

After: Section of "hump & hollow" landscaping complete  
After a well earned rest day it was a time for a change of scenery and also a change of task. The location was the Tongue Gill path, part of the very popular Coast to Coast route. The work was to build a section of stone path using large rocks that had been lifted to site by helicopter. This type of stone stepped path is known as "stone pitching".
The rock used has an interesting background as it came out of the ground lower down Tongue Gill during excavations for a  hydroelectric power scheme completed this year. The owner of the scheme generously donated the rock to Fix the Fells .

It was a very enjoyable and productive working holiday with lots of good quality work completed !

The National Trust runs a range of Working Holidays all around the country.  An opportunity for like minded people to meet, have a holiday and carry out conservation work with experienced staff.  The costs are fairly modest and cover accommodation in a bunkhouse, food during the holiday and transport between the bunkhouse and work site.  More information on working holidays can be found using the following link: Working Holidays

A Valentine to Volunteers

This week it is the turn of the South Lakes Upland Ranger team to write this blog and in light of the date it seemed like a great opportunity to remind volunteers that we love them !

Tackling erosion in the fells of the Lake District is a never-ending task and there is much more to do than the teams can possibly cope with. If it wasn't for volunteers we would struggle to keep on top of the maintenance of existing path work let alone undertake new projects.

There is one group of volunteers that is particularly close to our hearts; the 'Fix the Fells Lengthsmen'.  A  'lengthsman' is a traditional term for someone who looks after a right of way.
This group of  volunteers is involved in upland path work all year round and in all weathers. We frequently work with them and have got to know them fairly well. In fact two of our current team were first involved in upland work as volunteers under this lengthsmen scheme.

A work party with Fix the Fells Lengthsmen last summer on a
path project up Fairfield. A lovely day!
Lunchtime with lengthsmen: sheltering last week with a few volunteers on a
 work party near Blea Tarn.  Not such a nice day !
The volunteer lengthsmen carry out a range of important tasks. One of the main ones is the "drain run". This involves walking existing routes where path work has been carried out, clearing the drains  and clearing any gravel and loose material from the sections of " pitched" stone steps. It is also an opportunity to check the general condition of the paths and report back on areas in need of attention. The lengthsmen do an excellent job of coordinating their own drain runs and most weeks several drain runs take place around the Lake District.

They are also involved in project work which might include repairing or building new drains, pitching sections of path with rock and landscaping to define the main path and remove shortcuts.  Much of this is done in work parties with the upland path teams and some mini projects are carried out independently.

It is often a case of 'many hands make light work' and the progress from a work party day can be quite striking.

The results of the work party - a much better looking section of path. 
The lengthsmen are a fantastic group & always willing to get involved & help out even at fairly short notice. Last year, when weather conditions had delayed preparations, they helped us fill bags with rock just in time for the helicopter lifts that moved the rock from the screes to the nearby project site.

Today the South Lakes Upland Ranger team are out on a drain run with some of the lengthsmen and some potential new recruits, who will hopefully enjoy this "taster" day.

The focus of this blog has so far been our main group of upland footpath volunteers that we have got to know (& love) over the last few years. We are also fortunate to work with lots of other volunteers.

We sometimes have individuals who wish to work with the team, it might be just the odd day or other times a few weeks, perhaps using holidays.

Fairfield path project last summer.
Our volunteer centre at High Wray Basecamp frequently involves us with their volunteer groups. Examples might range from groups of college students doing outdoor courses to rehabilitation groups.

Other volunteers include groups that enjoy the fells in their leisure time.  Aware that they are contributing to the erosion problems they also want to do their bit to help.

(Weather looks nice here....but not for long....)
We usually run two upland footpath working holidays each year.  This involves up to 12 individuals joining us for a week's "holiday" working on our upland path projects.

It has only been possible to include a selection of volunteers that we have the pleasure to work with. However our message is the same to all volunteers:
"Thank you !"

Buried Treasure

This week it is the turn of the Upland Ranger team to write this blog.

At this time of year we are working mostly in lower level countryside, rather than up in the fells, and in recent weeks much of our time has been spent on a project at Moss Eccles Tarn. This is a picturesque glacial mountain tarn which was enlarged by the construction of a small dam and is situated not far from the village of Near Sawrey.

Moss Eccles Tarn
Beatrix Potter bought Moss Eccles Tarn in 1913 the same year she married local solicitor William Heelis. They kept a boat there and it became a favourite place for them to spend time in the evenings:
‘ William and I fished ( at least I rowed ) till darkness; coming down the lane about eleven. It was lovely on the tarn, not a breath of wind……’
It is also reputed to have provided inspiration for "The Tale of Mr. Jeremy Fisher".

Moss Eccles Tarn is a special place for wildlife today and is valued in particular for the wide range of aquatic and wetland plants and for its dragonflies and damselflies. It was bequeathed to the National Trust as part of Beatrix Potter's estate.

The tarn is classed as a reservoir and as such falls within the scope of the 'Reservoirs Act 1975' which means that it is subject to regular inspections by an engineer. Following the most recent report, it was recommended that the dam be strengthened and the height raised.
Moss Eccles Tarn dam before work commenced
The work on the dam wall was completed by civil engineering contractors. Once this part was completed, work on the 'reinforcing revetment' behind the dam wall was required. This had to be raised to be consistent with the new height of the dam and strengthened with stone pitching to ensure that the dam is capable of being 'overtopped'. This was identified as a good project for the Upland Ranger team since stone pitching is a technique that we often use for upland footpath work.

The first stage of our work involved digging out the old revetment behind the dam wall to a point where there were good foundations from which to start the new stone pitching. We also had to collect and transport several trailer loads of stone to the site for the pitching work.

Dam wall height increased & digging out the old revetment behind this has commenced.....

Our work behind the dam wall was divided into three sections, based on the shape of the dam wall, and our work was carried out on each one in turn.
One section of the new stone pitching progressing towards the enhanced dam wall
The stone pitching work carried out was very familiar territory for us. However, the specification for the work required that the part next to the dam also used concrete. This was very strange for us as we normally work purely with dry stone. In addition a geotextile fabric was used, along with soil and turf, to cover the top of the stone pitching work.
This meant we buried our lovely stone-work - the "treasure" referred in the title for this blog.
Geotextile fabric rolled back over a section of stone pitching with soil & turf now being added on top...
There wasn't sufficient turf available to cover all of the work done behind the dam wall and soil and grass seed were used for the remainder. It should start to green over early next spring and hopefully this time next year it will blend nicely in with the surrounding countryside, similar to the picture before work started above.
Our finished project... most of it now buried
Our last day on this project was at the start of this week and Sarah baked cakes to celebrate. Sarah created the "Moss Eccles" cake which instead of currants (which she doesn't like) has a filling of cranberries and white chocolate. Delicious!

Moss Eccles Tarn has been a very picturesque location to work at, although we are very lucky since we get to work in beautiful locations almost every day.

Itching to do some Pitching...

This week it is the turn of the South Lakes Upland Rangers to do the blog.

It may be helpful to first explain the title. "Pitching" refers to the stone step-like paths that are sometimes built in the fells to tackle erosion problems. The "Itching" relates to the fact that in recent years the team have not done much path work using rock and we were keen to do some.

In the last couple of years much of our work has used different techniques. These have included a subsoil technique, which uses compacted subsoil to create a hard wearing path surface, and landscaping techniques to define a sustainable path line and stabilise areas of erosion. These techniques predominately use materials near the path we are working on.

Subsoil path under construction last year 

There are various issues when considering rock for a path project, such as the proximity of suitable rock (we use rock local to an area wherever possible) and can we use it. There may be rare flora growing on a scree slope that is potential rock source that should not be disturbed. There may also be significant costs moving the rock if done using a helicopter (see blogs earlier this year) or it may simply be that rock is not the most suitable option.

The team's main project this year is on a path from Grisedale Tarn up Fairfield. Survey work concluded that an erosion scar that is developing was best tackled by 100 metres of stone pitched path. This means that the team has lots of pitching to get their teeth into.


Before work started: erosion scar developing
(Ignore rock on right, an old dry stone wall) 
In addition to getting rock flown by helicopter to the project site we were able to have a flat packed shed lifted there. This provides some storage but most importantly some shelter at lunch time when the weather is bad. The first job was to build & tether down the shed.

Project Fairfield "office" (not a bad location)
Once the shed was up we started on the stone pitching, taking a 10 metre section each. The first step was to dig in some of the biggest rocks at the bottom of each section to act as anchor for the rocks going in above.
Pitching in progress: looking down path at Luke & Tom in action
In addition to the stone work we also "landscape" out surrounding areas of erosion and finish off with turf and and grass seed to help the pathwork blend into the hillside.
Finished pitching plus landscaping
This project is progressing well and at the time of writing we are enjoying a very nice spell of weather.
Project progress as at end of this week

News from the fells

Rainbow seen from Glenamara Park
It's the time of year when the footpath team spend very little time in the lowlands (or in the office) and, unless you're a keen hill-walker, we are mostly seen as specks in the distance on the side of a hill.  At the beginning of May we led a Working Holiday teaching a group of very keen volunteers some upland footpath techniques at Glenamara Park, near Patterdale in Ullswater.
