UN13,140 was for us the first summit of a two summit day that included UN13,180. We undertook this hike with a little bit of information regarding the connecting ridge between the two peaks that indicated it went at 3rd class. The mileage and elevation gain estimates are based on starting from the campsite we've indicated in the approach section.
'So head out from camp and hop across the creek, cross the main trail and begin hiking up through the abundant flora & fauna that can be quite damp and quickly waterlog your boots. Take an angling path walking almost directly east to gain the first small basin at 12,060 ft. where the USGS map indicates there will be a small pond. The slopes are fairly steep, but there is little struggle with footing. There's actually a surprising amount of soft dirt between all the flowering plants. You may pass a few dwarf trees along the way and circumvent around the head of one very minor drainage with some exposed dirt and rocks.
It took us a little over an hour to arrive in the lower basin mentioned before to find there was no tarn or lake – just a relatively flat area where it used to be, a widening of the stream and a lot of marsh marigolds growing out of the marshy area. Hiking to this point, we had repeatedly stopped for flower shots.
Above this first basin, keep hiking on more lush tundra heading NE to a higher basin with a small lake just below 12,600 ft. Passing many more flowers, you'll arrive in this upper basin to find a lake of unique coloration – kind of a milky turquoise. Continue up a steep slope that has a game trail that leads north along a broad, flower-covered ridge with some willows. By this time, the distant views become something to marvel at. As we hiked by the willows, we thought we heard some strange sounds and unexpectedly, a group of deer arose from the willows and fled from us. There was no time to get their photo.
At about 12,800 feet, leave the broad ridge and cross the shallow basin on now flat, rocky rubble, heading for a saddle a little west of the first summit. There was no problem gaining the saddle on the rubble and we finished the walk out to the high point which lies at least one third of a mile SE of the maps 13,130 foot marker. This southeastern summit was undoubtedly higher than the one marked on the USGS map, so on Lists of John, it has been given an additional 10 feet in elevation by Gerry Roach & John Kirk. Take a brief break here and examine the choices over to UN13,180 or turn around and head back down as you came or you could try to find the path to the old mine between 11,600 and 11,800 ft. If you find it, you can follow it on down to the main trail and stroll back to your campsite. Much of this old mine path has been obscured by willows, etc., but an old feeder pipeline helped us follow it at times.
