For those that travel to/from Castleton via Winnats Pass, you may have noticed in recent times that there has been a few extra rocks on the road/roadside (plus there was a black car that had managed to end up in the gully, that has finally been recovered!).

DCC have posted this notice - from Monday 19th February 2024 to Friday 1st March 2024 the road will be closed between 08:00 and 17:00 to facilitate stone works on rock faces

There is always the old Mam Tor road to use instead.

When you consider what's been achieved in the Alps the Mam Tor lack of action seems a little feeble. It was a very useful road.

It's built on weathered shale which has the structural stability of porridge when wet....

Isn't it built on the missing part of Mam Tor? As for porridge - in my experience it's more ...er... stable when wet. However it's useful for growing hair on the knees.

To be honest, I've been watching and occasionally photographing the face of Mam Tor for the last ten years or so, and I can't say I've ever seen any significant change. I know the 'creep' of the landslide is supposed to be regular and constant, but again, nothing much seems to have changed downslope recently. Of course, that could mean it's 'stuck'...

A time-lapse lidar survey of the Mam Tor landslide, Derbyshire, UK.
David Hodgetts and Ernest Rutter
School of Earth, Atmospheric and Environmental Sciences, University of Manchester, Williamson Building, Oxford Road,
Manchester, M13 9PL. UK, (david.hodgetts@manchester.ac.uk)
Since 2004 a terrestrial lidar survey of the Mam Tor landslide in Castleton, Derbyshire, has been undertaken each
year. Using a Riegl LMSZ420i laser scanner, the data has been collected during the winter months, while the
vegetation is at a minimum, to ensure the surveys record a surface as close to the true geometry of the landslip
as possible. These surveys, when combined and viewed in sequence provide an accurate record of the landslides
movement over this time.
The main challenge in comparing yearly scans of a progressively moving feature (at up to 500mm/year) is to ensure
that each year’s scan is in the correct place relative to the others, to this end features outside of the landslip are used
as reference points to ensure consistent cross referencing of the landslip scans. In addition to this each year the
laser scanner is sited in the same position within the study area, to ensure the same areal coverage over consecutive
years.
In-house software called Virtual Reality Geological Studio (VRGS) is used to interpret and analyse the landslip
data (in both point cloud and triangulated mesh form), providing tools for comparing surface elevation, but also
to tracking individual features (such as individual boulders) from year to year allowing movement vectors to be
mapped across the area of the landslip. These vectors can then be compared with other measurements from total-
station surveys to act as a check on the validity of the lidar mapping approach. Topographic sections will be shown
through several parts of the slip to facilitate year by year comparison.
The landslide itself has formed within the Carboniferous Edale Mudstone Formation, is approximately 900m long,
270 to 300m wide and up to 20m thick. The landslip is estimated to be over 3200 years old.
