Fixing the landslide at Seldom Seen

As part of our work on the path at Seldom Seen we have also recently repaired a substantial landslide, around ten metres in length, which was washed away during heavy rain.

 Landslide from below

The first part of the job was to build the path up to it's original height. Using large stones (the same as we use for path building) a dry stone wall was built and the area behind the wall was filled in with material excavated from elsewhere on the path.

 Building up the revetment wall

The top side of the path had also been badly eroded by walkers trying to find a new route around the landslip. This area was re-profiled and a trench dug into the bank to take water away from the revetment wall and send it through stone drains at either side.

Once the revetment wall was completed and back-filled we covered the path surface with pinnel. Pinnel is a type of gravelly soil that compacts down very well to form a hard surface. This was dug out from around the washout and from the path above. It's very labour intensive to dig but gave the path a really nice solid finish.

Finally the top of the wall was turfed and landscaped to discourage people from walking on the edge and potentially causing damage.

The new section of path has made a huge difference and will help prevent the area becoming further eroded by people trying to pick a route around it.

Beyond the landslide a stone path was built incorporating stone drains to prevent water running down on to the area that had been washed out.

Continuing our work at Seldom Seen

Since our last blog post much of our time has been spent continuing the repair work on the path above the former mine workers cottages at Seldom Seen.

The photograph below shows a section of path that has started to erode quite badly. An old stone drain is at the bottom to allow a small beck to run across the path, but as the stone on the path above is very mobile this fills quickly with rubble. To stop further erosion and prevent the drain blocking up we decided that the best option was to pitch the whole section.

The stone drain was replaced and a new path was built.

Directly above this section the path had really gullied out, you can see in the next picture just how high the bank has been cut away once the new path had been built.

 Path repaired before landscaping

One of the most important aspects of our job is trying to blend a new path in with the surrounding landscape. The following photo shows the same section of path once the bank has been graded. A large quantity of soil had to be removed (which was used for landscaping elsewhere) to create a more natural bank this was then turfed and seeded to help stabilise the bank and also speed up the vegetating process.

Newly landscaped path

The next section that we worked on had suffered a serious landslide which can be seen in the following photographs.

Starting work on another section

The new path includes much better drainage to help reduce the volume of water flowing down the path which should help reduce the chance of another washout.

Completed path

To help prevent the soil in the bank falling back onto the path when it rains the side of the path has been edged with large boulders which will be continued along this full section. We'll also spot turf the area and put down plenty of grass seed to try and stabilise it all.

Starting work at Seldom Seen

As usual, our upland footpath work season began with a few weeks of filling bags with material to be flown by helicopter to the work site. We filled around ninety bags with rock from scree opposite the path where we're working.

 Heli-Bags filled and ready to be flown

The bags were flown a few hundred metres across the valley and dropped around each of the areas that we'd identified to be repaired.

 Unloading the first bag

Many of the sections of path that we're repairing on Seldom Seen are only around a metre in length and will prevent the path from getting worse. The section below had started to wash out and then deteriorated further after the winter flooding.

 Short section of path to be repaired

To stop the path getting worse, we built a short section of pitching and a stone drain. This will allow the water to be shed away from the path rather than run down it. Soil excavated while building the path was put downhill to fill in some of the gully caused by the flow of water. You can see in the photo below that rock has been dug in further along the path on the right hand side, to direct walkers onto one line and prevent the path getting too wide.

 Finished section of path

Fixing the drainage on this path is one of the main aspects of the job, as water running down it is starting to cause problems, and the path has shown significant deterioration over the last few years.

 Building a new drain

Another section that has badly gullied out can be seen below. The original short section of pitching and drain isn't really up to the job.

 Gullied section of path before repair

For this section, we moved the drain about a metre downhill to the bottom of the pitched path. This drain is fed into by a small beck, which was realigned with the new drain. The path has also been extended through the gully and incorporates another drain at the top of the path to shed any water running down the path. There's still some landscaping work (grading banks, turfing and reseeding) to be done but it's a big improvement on what was there and will help prevent it getting any worse.

Preparing for the path repairs above Seldom Seen.

Since our last post we've been getting ready for another season of upland footpath repair. Our main project this year is on the path above Seldom Seen, in Ullswater.

As a bit of a change from our usual blog post style, here we've documented our work using just a series photos from our Instagram account.

We're still fairly new to Instagram, having only joined in August last year, but it's proving a really good way to share our photos and chat with people interested in our work. You don't have to be on Instagram to view our photos, you can just click on the link here  www.instagram.com/ntcentralfells to see them. If you are on Instagram though, feel free to give @NTCentralFells a follow and we love seeing your comments too.
