Bob pointed out to me during a recent walk that the Viewranger App had a new feature, call Skyline.
For those who have not met this Android/Iphone mapping App that uses OS maps and allows one to either plan walks or track walks on OS maps with your tablet computer. If you look at the Walking Section of this Forum you will find examples.
Anyway the new feature allows you to point your phone camera to the horizon and get an image with features named on it. Here is an example taken from Spittal point in a northerly direction.
