Orchard Common and Drystone Edge Geological Field Trip Notes

The following are field notes from a visit to the valley just to the W of Drystone Edge to inspect the Upper Namurian, especially the Ringinglow coal outcrop and associated seatearth and marine shales (contorted beds). The locations were logged using a Garmin GPS60, and may be downloaded in GPX format. The points are named […]

Using Mapyx Quo to Create Virtual Field-trips with Google Earth

This post describes an approach I have adopted to create virtual field trips using Mapyx Quo as a starting point to produce interactive annotated virtual field-trips. The initial impetus was to look at the geology around Millers Dale, specifically at the outcrops of the Millers Dale Lava Beds. Details of this trip will follow in […]

LED Caving Lamp – Adapting an “Oldham” Caplamp

Some incomplete notes from a recent conversion of 3 old cap lamps to run off white LEDs extracted from a cheap (yet astonishingly bright) headtorch and powered by Lithium-based cells salvaged from an old laptop battery. One of the 3 caplamps was from a 1991 Apex 2 and the others were ex-NCB pit-lamps of unknown […]

GPS/GPX Waypoints for PDMHS Newsletters 122-133

The download below is a GPX file suitable for GPS and digitak mapping software. The locations are of sites mentioned in the Peak District Mines and Historical Society newsletter editions 122-133. These are not sites I have GPS-located but have been transcribed from grid references in the newsletter. These are sometimes 6 figure OS Grid […]

Using the British Geological Survey WMS Service with Mapyx Quo

Major kudos to BGS for making their 1:50,000 geological maps available online including via a WMS Service. I’ve been struggling with scanning BGS maps and importing them into Mapyx Quo for a while. Its an arduous process and the scanned maps contain the roads, placenames etc as well as the OS topographic map I have […]

GPS Waypoints for Bradwell Area Caves and Mines

The following GPX file uses data from HNH/PeakDistrictCaving, specifically their index to the Bradwell Catchment (PDF). I created this after a trip around Bradwell Dale, mostly looking at the geology, and compared with a set of GPS waypoints and the tracklog. Based on this, I am sceptical of the accuracy of the Grid Ref for […]

GPS Waypoint File for Stoney Middleton Dale Caves and Mines

I came across a list of grid references for Middleton Dale caves on the Chesterfield Caving Club website and converted them to “GPX” format for use on my GPS and digital mapping software. Here they are: chesterfield-cc
