It seems like there are basins with the timber in it so focusing on the fringes of the timber with the spotting scope would be important but those are below 10,000 feet . But above that the basins have no trees in them and go up to 13,000 feet and are mostly grass and rocky....These would be very tough to get up on top of..... I guess i just need to get out there and do it...........I will be talking again to the biologist again for my unit to get a better idea where to start. Thanks for all your help.....
