Northeast of Tucson, Arizona, is a land of rugged ridges and deep canyons. Rising up between the breathtaking Sabino Canyon and neighboring Bear Canyon is a jagged peninsula of land known as “Blackett’s Ridge.” Lining this ridge, trending roughly east-to-west and rising in elevation from lowest to highest, are frequently-visited UN 4409, the sinister-looking, UN 5001, famous Thimble Peak, and often-overlooked UN 5420.
This specific peak has a bit of an identity crisis. When locals says they’re “doing Blackett’s Ridge,” they typically mean they are hiking the trail from the Sabino Canyon parking lot to the terminus of the trail – just below the summit block of UN 4409. (Few have reported traversing the entire jagged line of Blackett’s Ridge.) USGS maps indicate a landform name of Saddle Back, though if you mentioned you were going to the summit of Saddle Back, most locals would have no clue what you were talking about. If Blackett’s Ridge could be said to have a summit, it would be UN 5420. So, for the purpose of this page, we’ll call this officially un-named mountain UN 4409.

Per Friends of Sabino Canyon:
From the intersection of Kolb Road and Tanque Verde Road, turn right on Tanque Verde and travel less than a mile to the intersection with Sabino Canyon Road. Turn left onto Sabino Canyon Road and travel north 4.5 miles. The park entrance will be on your right, just after the intersection with Sunrise.
The Sabino Canyon parking lot can fill up on nice weekends, so get there early or park on the side of the road near the entrance.
