A couple guys on Blue asked for run time and distance, so I thought I'd post it here too.
A quick run down:
Leave trailhead on S22 at 9:30,
Grapevine Canyon - 13.6 miles, 1.5 hours,
S3 - 14.2 miles, 20 minutes,
From Landfill to Ella wash/S22 intersection - all washes in trail run included. (total guess: 2 1/2 hours, this may be way off on long side)
S22 to Calcite Mine trailhead - about 5 miles, 10 minutes (again a guess)
Calcite Mine trail 3.8 miles, 2 hours - there and back.
We should be back on S22 near N33 16.868 W116 05.795 around 4PM. Options here to continue as suggested in trail run or head home if you're stretched for time.
