The following page should provide some explanations of the terminology used in the site. If you require any further explanation, then please get in touch.
The OS Openspace interface allows for markers and routes to be placed on 1:50000 scale maps, as found on the OS Landranger series. The main map for each mountain/corrie described shows the spread of approximate starting points for each descent listed. Whereas I have made some attempt to locate these markers at the start of the descent, they should be treated as marking the approximate start position of the descent line.
Each individual descent line has an approximate start (green flag), and an approximate finish marked (chequered flag). The line plotted between these points is to give a general indication of the line of the descent. The marker indicate the start and the end of the described line - it may be possible to continue beyond the finish marker in good conditions.
Where possible, and eight figure grid reference is supplied, along with the two letter 100km square reference. This gives a start location within a 100m x 100m square. The top of many of the descents listed may only be a few metres wide. As a consequence, the grid reference should be treated as an approximate location for the start of the descent.
The start height of the descent line is the start height of the line as described, in metres above sea level. It may be possible to descend from higher up the mountain to reach this point.
This value (in metres), is the usual vertical descent possible of the line. In good conditions, it may be possible to continue beyond this point. Often this value indicates the point when the steeper sking ends, and may be a logical point to stop so that other lines can be included in the day.
This is the aspect of the descent line. It is labelled "General Aspect", as it is not uncommon for a line to feature more than one aspect in it's length.
Where a line had a climbing grade, it is reasonable to suggest that you should be proficient at climbing the grade. Sections that you can slide over in descent may feel a whole lot more serious when climbing back up. You may also wish to consider whether it is worth carrying enough climbing gear to bypass a difficult section. That's obviously up to you!
An explanation of the values entered for the "climbing grade" section are as follows:
This is an interpretation of the grade, based upon experience of ascending many lines of similar grade.
