Navigational Questions & Answers / Re: Aspect of slope!!!
« on: July 17, 2012, 07:09:36 AM »
I think of the aspect of slope bearing as only being able to go straight down the contours. Like a magic ball that can only roll down and across the contours at 90° to them. Rough sketch below but might give an idea?! If you stand on my rough ridge and take a bearing down the balls paths it will be different at different points along the ridge. You can match the bearing up to the actual map with the edge of the compass also crossing the contours at 90°. Confused, sorry!
On courses I usually find a ridge or similar that curves enough so the bearings are very different. Like other aspects of navigation it comes as a 'penny drops' moment after a few goes.
