This is considered the "classic" approach route for Edwards. It can also be used as a route for Grays Peak. From the Waldorf Mine site, walk along the main road to the south until you come to the crossing of the unnamed stream that drains the western slope of Mt. Edwards. It's about .3 mile. No need to cross the stream if it is flowing. Turn right (west) and begin heading up the drainage. A trail leads west for a little while then fades. Watch carefully for an old mining road that has become somewhat obscured that works up the drainage, staying on the north side of the stream and well away from it. This track will help you skirt the willows found along the stream. Pick up a second track that will lead west even farther, again, skirting willows on the north side of the stream. These tracks can be faintly seen on GE.
At 12,300 feet, you'll be past the willows. The basin in late June and July holds many wildflowers. For the next 250 vertical feet, the slope will steepen and become rubbly. In the earlier summer season, the main drainage may be filled with snow and offer both a snow climb and nice glissade descent if you like. Above that section, the slope angle relents a little and the terrain becomes mostly tundra with embedded rock and minor scree. Take the path of least resistance all the way to the summit ridge. The south side of the center drainage seems to have more tundra. If interested in tagging McClellan, you can veer right to the saddle between it and Edwards. The ridge connecting them holds no problems. The FSTopo map 2016 shows that a few hundred feet below the summit, you should intersect a portion of the Continental Divide Trail. Since we have not been here since 1988, before this stretch of trail was put in, we cannot verify that you will encounter the trail as the map shows. There is no evidence of it on GE that we can find and it seems a little strange that the trail would swing out onto this east face. The Trails Illustrated map seems to indicate it stays on the ridge south of Edwards. If anyone has a report regarding it, please send it to us.
From the summit you may enjoy a spectacular view of Grays, Torreys and Kelso, and Stevens Gulch far below. Return as you came or it is possible to ridge hike south to Argentine Pass, then on to Argentine Peak with little difficulty. Overall, we rate this hike an easy Class 2 mainly because of the steepness. Some may consider it a Class 1 hike.
