Lording over the western edge of Spencer Basin is bold and beautiful peak with no name – UN 13434. This peak’s rocky and rugged eastern aspect looms over the basin, verdant and full of wildflowers in the summer. Hidden from view to visitors to the lower reaches of Mountaineer Creek, visitors to the higher reaches of Spencer Basin enjoy the rocky mass of UN 13434 jutting against the San Juan sky. One of the highest 300 peaks in Colorado, the great secret of UN 13434 is its gentle (albeit steep) southern ridge that provides a surprisingly smooth ascent of this anonymous Thirteener.
Views from the top of this nameless mountain include close-up shots of nearby neighbors Mount Rhoda and Kendell Peak and distant vistas of the Sneffel’s sub-range. Engineer Mountain sits lonely and defiant to the west, while the Granadiers rise with their seductive alpine curves to the south. History buffs will enjoy learning more about Highland Mary Mine first-hand and in the summer months, the wild flowers on the slopes of this peak will delight.

Be sure to look for a left turn off of this road that crosses Cunningham Creek just before reaching the parking area. If the road starts switchbacking, you've gone too far. The parking area should be visible on the left and below.
This peak can also be accessed via Deer Park. To reach the Deer Park trail, use the Kendall Mountain Trailhead in Silverton at the intersection of 14th Street and San Juan County Road 33.

Weather & Seasons
Summer in the San Juans is heavenly, with warm sunny days and cool, crisp nights. As with the other mountainous areas of Colorado, the afternoon thunderstorms mean summertime hikers need to leave the summit by noon. The San Juans are well-known for thawing out later than other parts of Colorado; it is not uncommon for an ice axe to be required year-round on certain routes.
The town of Silverton and surrounding mountains receive massive amounts of snowfall in the winter months. Avalanche chutes abound in the area; in the summer, the wounds from the previous snow-season’s avalanche activity are evident. Exercise prudent snow sense in these mountains when snow cover is present.
