I'd say about 2 1/2 hours. I'm assuming they started from Camp Hale, which is between Leadville and Vail. To see Shrine Pass (basically a dirt road) you can go up I-70 to Vail Pass and get off for the rest area. After you cross the bridge and descend to the rest area there will be a right hand turn onto a dirt road. That takes you to Shrine Pass, McCallister Gulch is on the back (west) side.
