Discovering silver maple

On the hill on lunch hour:

1. A maple, but leaves not like a sugar maple.  More in the direction of oak leaves.  Multiple buds at leaf base.  Buds of what? Bark in peeling strips.  No seeds.  Silver maple? Blouin book says silver maple branches rise, then dip, then angle at tip.  I think I can see that.  Branches not horizontal, not good for climbing.
2. Tree behind #1, also shaggy bark, branches less sharply upward.  Like #1, leaves long and pointed, inclined to three lobes.  Leaf stems are red, while on #1 they are yellow-green.
