Ok, I had an idea for a hike around the Mummy Range, mostly in RMNP, but I don't know if it is possible.
My plan would be a leave my car at the Lumpy Ridge or Lawn Lake trailhead, then shuttle or hitch to the Timber Lake tralhead and start hiking up the La Poudre Pass Trail, past the Long Draw Reservoir, and turn onto the Mummy Pass Trail. Once over the pass the trail leaves the park and ends up on private property on the South Fork Cache La Poudre River. (The Koenig Ranch?) I would need to cross the valley of the South Fork Cache La Poudre, and cross the ranch, to reach the Stormy Peaks Trail and ultimately hike back to the car.
Can one cross from the Mummy Pass Trail to the Stormy Peaks Trail as I describe? (After all, these well-known trails DO cross his property.) Or is the rancher persnickety? I suppose I could bushwhack across the valley before the trail leaves the park, but on the map that doesn't look like fun...
