This is a fairly stiff climb up a dirt road that climbs over 1300ft in less than 4 miles. The road starts Approximately 1.5 miles past the Deadman's parking area.
From the parking lot, ride up Cement Creek Road, cross over Cement Creek on a large culvert, and switchback up. On the right will be a well worn but unmarked shortcut - take this or continue to the marked junction of Reno Divide Road 759. Go right and climb steadily for about 5 miles to the top of Reno Divide.
From the top, you have several options. Trail 422 (Flag Creek
) heads downhill due southeast. Trail 607 (Reno ridge) heads due south on doubletrack that eventually changes to singletrack. If you parked at the deadman's gulch parking area, Reno Ridge is a good alternative that will get you directly to the Deadman's trail/switchbacks faster if weather is threatening.
