Adaptation of the ATES scale to trip planning in general
What kind of trip is this?
- Simple:
- easy travel:
- well-mapped, obvious trails
- poor trails but in familiar territory
- simple and short cross-country travel in familiar territory
- easy navigation
- favorable weather
- low risk exposure (e.g. below Class 3 scrambling, Class I whitewater with warm temps, easy river crossings, etc.)
- level of exertion well below physical limits
- low commitment - easy self-result/bail options
- close to well-resourced and responsive first responders (e.g. Yosemite, Front Range)
- easy travel:
- Challenging: one or more of the following:
- challenging travel:
- poor/unmapped/unmarked trails in unfamiliar territory
- complex or extensive cross-country travel
- difficult navigation (fog/snow, thick brush, canyons, etc.)
- unfavorable weather
- moderate risk exposure (e.g. Class 4 scrambling, Class II-III whitewater or cold water, difficult river crossings, etc.)
- level of exertion close to physical limits
- moderately committing - some self-rescue options, but some committing sections, or long/difficult bails
- external rescue likely to be difficult and take a while, e.g. Alaska
- challenging travel:
- Complex: many of the above, or one or more of the following:
- very difficult travel:
- off-trail with no established beta
- extreme brush
- dangerous weather (extreme cold, etc)
- high risk exposure (e.g. Class 5+ climbing, Class IV+ whitewater, etc.)
- “red line” levels of exertion for extended periods
- highly committing routes with limited or no self-rescue
- very difficult travel:
