Coming from sea level of the Midwest the day before, our hike at starting altitude of 8,800 and walking a vertical mile on the hike was a poor suggestion to us tourists. I have never before or after experienced this severe shortness of breath & overwhelming fatigue that hiking at this altitude the morning after arriving in Elko from sea level caused. We were told by locals this was a nice leisurely hike, lake at the top 2 mile hike roundtrip. Take a bottle of wine, enjoy the coolness at the top, etc. No one mentioned being bent over gasping for air while we could still see our car parked in the parking lot. Beautiful region, great trail, river crossing etc. , but is a huge challenge to those new to HIGH High Sierra.
