I'm planning a river trip in Utah (Green River)in late August/Early September and have been doing some (basic) research on trees etc for use as fire fuel. Just to make it clear that the fire will only be if there are no restrictions and will be used near the waters edge in a fire pan. Obviousely if restrictions are in place then no fire

Secondly my interest is in case of problems (lose stove/boat etc)and the fire becomes "survival" oriented. What is the best wood that is likely to be found (tamarisk?)and can anyone advise on likely natural tinder that would generally take a spark from a firesteel?
As ever thanks for your advice
