From Tyler McMillen's Tucson Bouldering:

The Aspen Trail boulders are great for summer bouldering, probably the best in town. A good summer day can be had by climbing at the AM/PM Wall in the morning, heading over to the Mango Boulder in the afternoon, and finishing the day off at the River Boulder. This will keep you in the shade all day.

If you haven't been to this area of Mount Lemmon yet, it's well worth the trip. Beautiful area, a stream, trees, and lots of bouldering potential, in addition to what has already been documented.

Again, if anyone else has route or area info that can provide more details, names, ratings, etc., please contribute what you can.

Getting There 

Drive to the end of the road past Summerhaven (Summerhaven Road). Park there. All three walls are within 15 minutes hike of the parking lot.

Please post any relevant history, info, etc. and I can update accordingly. These are the lines my friends and I have climbed over the past few years, and I thought I'd post them. A more comprehensive guide to the bouldering in southern Arizona can be found at oldpueblobouldering.com/.

The color code for the topos is as follows:

VB-V2: Green
V3-V5: Blue
V6-V9: Orange
V10-Above: Red
Project: Yellow

Grades are proposed as a range of two (possibly three) in order to accommodate the lack of consensus on nearly all of the problems. They will be edited from time to time as to reflect the opinions of those successful in repeating the problems.
