Analysing terrain data
The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
This is an uber-gnarly old school DH line that begins and ends on Aspen Slalom.
It's even steeper than aspen slalom, with eroded drops and challenging trenches. Sources: http://cdn.deervalley.com/web/Areas/WhatToDo/Content/pdfs/BikeTrailDescriptions.pdf http://cdn.deervalley.com/web/Content/pdf/planning/trail_maps/DVRSummerTrailMap.pdf
