where Tucson
the hike     How about a hike on Mount Lemmon to escape the summer heat? At over 7500 feet elevation we will be as high as some of the trails in Flagstaff.
    Start at the Mint Spring trailhead, making our way through a heavily burned area with a lush undergrowth of ferns. After about 1.7 miles we will reach the Marshall Saddle, a crossroads of several trails. From here we will take the Marshall Gulch trail down into a valley with running water. After another 1.2 miles we will arrive at the Marshall Gulch picnic area where we’ll stop for a restroom and snack break. Then we will head up the Aspen trail which takes us through riparian areas and pine forests, past bare granite walls, arriving back at the Marshall Saddle after 2.2 miles. From here we will follow the Mint Spring trail back to the starting point.
    Mount Lemmon can be very pleasantly cool in the summer, but it is also susceptible to sudden monsoon storms, so come prepared.
