Oreamnos americanus
Not a true goat, but the best climber on the continent.
2–3.5 in long. Cloven, boxy, toes splay widely. Squared-off front edge. Deep rubbery pad center. Tracks on impossible-looking rock.
Alpine cliffs and talus above treeline. Northern Rockies, Cascades, coastal Alaska.
Diurnal
Alpine grasses, lichens, shrubs
Mountain goats crave salt and will follow hikers for it — a reason to keep distance.
Should I be concerned?
Keep 50 yards away; habituated goats can get pushy.
