I cannot for the life of me seem to be able to determine the species of these leaves. There's gotta be someone here who's good at this. Thanks!

1. Silver maple
2. Tulip tree
3. Possibly sumac if there was more to the leaf

If you live in CO, those are probably all ornamental trees since they're deciduous and not willows or cottonwoods.
Silver maple and sumac might not actually be right but that'll give you some leads.

Determined that 1 is a silver maple and 3 is a rowan ash, but can't figure out what 2 is. Not a tulip tree

#2 is a Green Striped Maple. Post any botany questions - I'm always happy to answer them.

It would help a lot if you would post what part of the country these are from.

Hard to say - not up on my CO trees. Could possibly be a willow, either Peachleaf or Pacific. A better view of the edges of the leaf (to see if they are jagged), as well as a ruler for scale would help.

It's around 4 inches long, 1.5 inches wide, and the edges are jagged with lots of little "jags"

Other possibilities include the Wild Plum and some type of Alder. This is a very, very generic looking leaf.

type of elm I think

The first is a silver maple, more likely a hybrid of one though

second, no idea. First thought was stripped maple.

third is a mountain ash


going off what I know of Ontario trees. apparently we don't share much.
