Although I am careful about what goes on inside my tent to avoid bear encounters, I have a few rituals I perform whenever I land at the shore of a campsite to assess it's potential as a safe bear free area.
!. I check the fire pit, is there even a fire pit, is there vegetation growing in it, is there junk in it, half burnt un split wood in it.Is there a some dry split wood left there for the next camper, these all tell me about the type of people who use the site or if it's even used at all.
2. I check out the latrine. Is it heavily used. Is it used as a dump station for uneaten food.How long ago was someone here.
3. I walk the site, has the firewood been picked over, have folks cut trees in the sites perimeter, lots of foot trails, no foot trails, no game trails, no scat, fish scales, trash, if they leave newspaper for starting fires, is it from a city or rural area.
If I feel the site is not in good condition I will paddle away and bushwack on a rock if necessary. I always sleep well at a good clean site.
