Here are two small trees I saw from an upland forest walk.
The one tree has yellow flowers and the chestnut-looking leaves.
The other tree has large green fruit--I was thinking some sort of crab apple. It only had one or two leaves remaining so I could only get 1 good picture.
Thanks in advance!

First one is a witch-hazel Hamamelis.
Second, yes, a crabapple.
