Approaching from the south
Marble Peak manages to stand gracefully in the Santa Catalina Mountains of southern Arizona despite being criss-crossed by mining roads and riddled with underground copper tunnels. Deeply furrowed by drainages, this double-topped peak sits due-north of the cabin communities of Loma Linda and Summerhaven high on the slopes of the Catalinas not far from the top of Mount Lemmon. Much of the Oracle Ridge area was heavily impacted by the 2006 Aspen Fire, though Marble Mountain was thankfully spared. Views from the top include the summit of Mountain Lemmon, including the Mount Lemmon ski area, Mount Bigelow and the Oracle Ridge Highpoint.

This peak can be accessed by trail or service road from at least three different directions, though most visitors would be content to gain the summit from the General Hitchcock Highway, also known as the Catalina Highway or the Mount Lemmon Highway. The Oracle Ridge Trailhead, near mile marker 25, can be reached within an hour of downtown Tucson. Take Tanque Verde (often pronounced “TANKy VURdy" by the locals) diagonally across the northeast edge of town to East Catalina Highway. Follow East Catalina Highway North for about 4.5 miles to the Forest Service boundary. Here the road becomes the General Hitchcock Highway…or the Catalina Highway…or the Mount Lemmon Highway.
Note that the highway is paved, but longer vehicles (22 feet or greater) or those towing a trailer may have difficulty negotiating tight curves.
Along Oracle Ridge
I will post a simple route via the Oracle Ridge Trail, including Summerhaven Benchmark, shortly. I encourage other SummitPost members to attach routes they have used to the summit of this peak.
Use of the Mount Lemmon area, including the Catalina Highway, is subject to a $5 vehicle / use fee.

for detailed regulations governing use of this area.
Note that the area immediately surrounding Marble Peak is marked on the map as private property. The Oracle Ridge Trail provides a public right of way through this area. While the mountain appears to have at one time been mined for – not surprisingly – marble, the more recent venture was copper mining at the
Oracle Ridge Mine. While production stopped in 1996, efforts are underway to re-start small-scale, underground mining of copper below/within Marble Peak.

Weather and Seasons
Blazing Arizona Sun
| || Marble Peak is a year round mountain. Predictably, spring and fall would be delightful times to visit this peak. In the summer, the heat blasting up from Tucson could make it hard to escape the heat, but at more than 7,600 feet above sea level, the peak offers some escape from the heat. Winter should typically be sunny and pleasant, but can be cold, windy and snowy. Occasional snowstorms slamming the Santa Catalina Mountains might close the “highway with many names,” or at least encourage the Forest Service to put a “4x4 or chains only” rule in effect.|
Before planning a trip to Marble Peak, I suggest checking the weather both for Tucson, Arizona, as well as for Mount Lemmon or Summerhaven, as the road to the peak will cover both extremes and everything in between.
