WebFor the slope meter method (and also the iPhone apps if you're brave enough to trust them!), the best approach is to lay a ski pole on the slope and place the inclinometer on it. You can also use your ski poles to give a rough indication of slope angle. I like the method described by Bruce Tremper, in his book "Staying Alive in Avalanche Terrain". WebLandslides are shown on our geological maps and we maintain the National Landslide Database, which has over 18 000 records of landslides in Great Britain. When required, we also work on international disaster assistance projects using satellite imagery to map and characterise landslides that can be used on the ground by local relief agencies.
