A rare pocket of sugar maple on this south-facing talus slope. The last photo is, of course, a separate individual but included because it shows evidence of recruitment and was immediately adjacent to the trunk and so provides extra evidence for the correct ID, seeing as how the other leaves are quite a bit higher up in the canopy and hard to see.
