You know, you're right about the trees. The trouble is I'm not scaling them down at altitude. I think the scale is right lower down, but in real life the size of the trees gets smaller as the altitude increases, right? I think the tree line in the Yosemite area is about 10,000 feet. The top of El Cap is 7569; the valley floor is 3971.( The really big Douglas Firs and redwods are around 5000, I think.) The trees at the elevation of the top of El Cap are pretty shrunken , iirc. Still trees, but nothing approaching the 150 ft+ of the big douglas firs. I sort of envisioned the stuff on the vallery floor as being about 30-60 feet high; I suppose the stuff at the top shouldn't be any higher than 20-30 ft, or about half the current size, at biggest.
