Reply to comment by lovesmtns in Rattlesnake Ledge Trail. I love how close to Seattle these views are. by jhawkweapon

I love how flat the upper valley is from this view. Glaciers we're incomprehensibly giant.

I have pondered those flats many times. Obviously they aren't the bottom of the glacier valley, so they must be moraines. I haven't figured out why they are so flat, but obviously again, it was done somehow during the glaciation :):). OR, maybe they were the flat bottom of the glacier valley, and the rivers further eroded around them. Would love to have been a geologist in another lifetime, what stories they have to tell :).
