Granite Boulder and Puma Hills
Granite Boulder and Puma Hills from the UN 9111 summit

This cool little rocky wonder is easily one of my favorite 9,000 footers near the Colorado Front Range metropolitan areas. This steep but petite jumble of granite offers up a lot of bang for the buck. From a distance, it may appear this peak would not permit a non-technical acent, bit the southeast aspect offers a hidden surprise. Indeed, a dog can ascend this nifty little peak where the difficulty does not exceed a stiff YDS Class 2+.

The surprisingly broad summit plateau is the perfect place to kick back and take in the views or explore a bit. The sheer walls of the peak dropping away from the summit plateau allows for cool aerial views of the surrounding valley. Close-up views of the Tarryall Mountains, particularly South Tarryall Peak and McCurdy Mountain, delight. Fourteener Pikes Peak shows itself in the distance to the southeast, while high Thirteener Bald Mountain pushes its bulky mass toward to sky to the west.

There is little red tape governing recreational use in this part of the National Forest and there is no fee to access this area. Adhere to LNT (Leave No Trace) principals, observe fire ban when in effect and do not harass wildlife or allow your pet to do so.

When ascending the peak via the Spruce Grove Campground, as most visiters will do, please be respectful of those camping. Give them their space and privacy, even as you must tiptoe through the campground to reach the peak.

Note: The primary route to the summit of this peak requires walking right through the Spruce Grove Campground on a social trail. It is recommended that this peak be visited when the campground is closed, and certainly not in high season (mid-summer). This will give campers some quiet and privacy and avoid any awkward moments as you walk through the campground.
Summer: The air temperature may be a little warm in the summer and the area quite crowded.
Spring: The snowpack is less deep here than in the high country and melts out faster than higher areas to the west. None-the-less, expect post-holing through unconsolidated snow drifts in the trees.
Fall: The aspen coating the slopes of area peaks make this area a golden-hued heaven in the fall. The Tarryall Valley is a special autumn treat.

Winter: Thanks to proximity to CR 77, this peak is accessible in all but the most epic snowfalls.

Class 3-4 route up the wall

I have climbed the upper wall unroped from the campground in like 1-2 hours. With care to find the easiest route, rock should not exceed class 3, but the most obvious route is class 4. Route goes diagonal left to right from about the middle of the upper portion of the wall. The backside ascent described above is not nearly as rewarding as the scramble up the front side, in my experience.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
