Milepost 235 & 237  The famous "Last Tree"
As you begin to climb in elevation toward Chandalar Shelf, the trees thin and eventually disappear altogether. At this high latitude, the tree line is extremely low, about 2,250 feet. Trees cannot grow at a higher altitude north of here. As you begin your climb up Chandalar Shelf, this is the first major incline toward Atigun Pass. The views are absolutely fantastic!

This is the highest road pass maintained year-round in Alaska.
