LoJ: #420 (Pre-LiDAR #430) / 13,275' Darley Mountain Formerly UN13260.

There are two main access routes for the summits located around Engineer Pass and American Flats; one from Lake City, the other from Silverton.

These directions begin from Lake City. From Gunnison, go west on SH50 to the intersection near the beginning of Blue Mesa Reservoir with SH149 and turn south. From Montrose, drive east on SH50 to the east end of Blue Mesa Reservoir for the same turnoff on SH149. Drive west and south on 149 to Lake City, just over 45 miles from the previous intersection. Once in Lake City, watch for either 3rd or 2nd street. Turning west on either will take you to Bluff St. in two blocks and a left turn (south). 2nd St. is considered the "official" access to CR20 which heads west following Henson Creek, but if you take 3rd St., it passes by a nice city park with restroom and picnic tables for those who need a break before proceeding further.

Once on CR20, drive 9.1 miles west to Capitol City on a graded, gravel road passable to passenger vehicles. On the Gunnison National Forest map, this road is labelled as BLM3303. At 5.2 miles into this drive, you'll pass the Nellie Creek Road (FR877) which accesses Uncompahgre Peak and several 13ers located in that area. At Capitol City take the left fork which is the "Alpine Loop Road" that will lead over Engineer Pass, but you won't be driving quite that far. This is the continuation of BLM3303. On Google Earth, this is still CR20. Continue driving west past the "Rose Cabin" on the old USGS map. (Note: About 1500 feet east of the Rose Cabin is a solar powered vault toilet on the south side of the road, frequently used by visitors to this area.) From that vault toilet pullout, it's about another 3.6 miles west (appx.) to our suggested parking spot and trailhead for American Flats, which is nothing more than a pullout at the coordinates provided. The main goal is to locate the start of the trial that heads north across American Flats and park off the road enough to avoid blocking the frequent 4WD, ATV and ORV traffic. If you come to a beautiful log cabin perched on an overlook of the valley with a foot bridge leading over the creek to the cabin, then you still have another 1.75 miles. The parking is above treeline.

From Silverton: From the Town of Silverton, drive east on the main road through town to where the paved road splits one block past the courthouse and veer right onto the blue-signed County Road 2 (set odometer here) for 4.2 miles of nicely graded dirt road to Howardsville. (On Trails Illustrated map #141, this road is labeled #110. Pavement ends after 2 miles. This road is also known as "The Alpine Loop Road and BLM 4500.) From the Howardsville intersection, continue north another 4.3 miles to the old site of Eureka. The road will cross to the west side of the Animas River and continue up a steeper shelf section. The road begins to get a little more difficult and enters a more narrow section of the Animas River canyon. At about 10,740 ft., the valley begins to widen out again. In that location, another road heads off to the left for Picayne Gulch. It is possible to reach UN 13,075 and Hanson Peak by going up this way, but the lower section of this road is intensely steep, so only for lower gear ratio 4WD vehicles. For the American Flats TH, stay on CR2 and follow directions & road signs to Engineer Pass. This will REQUIRE 4WD. The 4WD track circles the west side of Engineer Mountain, crosses the pass and then begins its descent toward the upper reaches of Henson Creek. When you reach the summit of Engineer Pass, the proposed trailhead is only about 1,600 feet east of the pass.
