The limit of timber in the Salt Eiver Eange seems to be abnormally 

 low. In the Wyoming Eange it agrees quite closely with the hight in 

 other ranges in the same latitude. 



No peaks in the Bear Eiver Eange are above the limit of timber, and 

 the peaks in the other ranges in this rectangle do not reach it.
