Is it right for you?
K 49 is a modest summit tucked between big 14ers and 13ers above North Halfmoon Creek, west of Leadville, with commanding views all around.
The trail takes you to 11,600 feet; then you bushwhack west across two streams to the creek, cross it, and walk easy slopes up the north side to the ridge and the top. It is Class 2. It can also be reached from the Highway 82 side over a pass from Lackawanna Gulch, which is longer.
The round trip is about 8.5 miles with 3,200 feet of gain from the North Halfmoon trailhead (4WD).

Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.
Getting there
North Halfmoon Creek
From Leadville, drive about 3 miles southwest on US 24 to where it bends sharply south. Turn right (west) on Highway 300, cross the railroad tracks and go 0.8 mile. Turn left on County Road 11 and go 1.3 miles to a fork. Bear right to stay on CR 11, which becomes Forest Road 110. Follow it about 5 miles past three campgrounds to the Mount Massive trailhead, about 7 miles from US 24.
Low-clearance cars should park at the Massive trailhead and walk the road. With more clearance, drive about 2.1 miles farther west to the turn for South Halfmoon Creek. From there, FR 110 is true 4WD, with a steep rocky hill right away. After about half a mile, the North Halfmoon Creek trailhead parking is just before the road crosses the creek. Campgrounds along Halfmoon Creek fill on summer weekends.
