Lake Oesa is a body of water located at an elevation of 2,267 metres (7,438 ft)[1] in the mountains of Yoho National Park, near Field, British Columbia, Canada,[2] while a trail at the far end of the lake leads to Abbot Pass.
The lake gets its name from a Stoney language (Native American language) term for 'corner'.[3] It can be reached via a 3.2-kilometre (2.0 mi) climbing trail which starts at Lake O'Hara and ascends approximately 250 metres (820 ft).[4][5] An alpine trail along the Yukness Ledges connects Lake Oesa to nearby Opabin Lake.[6]
