Mount Lemmon

This peak in the Coronado National Forest of Arizona reaches 2,791 meters above sea level and consists of granite formations that define its ridges and slopes. The landscape shifts from dry desert flats to denser conifer forests as elevation increases, bringing cooler temperatures and different plant species.

The summit received its name in honor of Sara Plummer Lemmon, a botanist who documented plant species in this area during an 1881 expedition. The road to the top was developed in the 1930s to provide access for recreation and fire control.

The SkyCenter takes advantage of dark skies and dry air for nighttime observation, offering programs that bring astronomy closer to visitors who come for the view. Clear conditions at this elevation attract both researchers and amateur stargazers working far from city lights.

The Catalina Highway winds upward on switchbacks and provides access to hiking trails, picnic areas, and camping spots along the way. Drivers in summer should bring warmer clothing, as temperature drops noticeably with elevation.

The drive upward passes through six distinct ecological zones, equivalent to a cross-section from Mexico to Canada, experienced within a few dozen kilometers. At the upper end sits the southernmost ski resort in the continental United States, allowing for snow activities during winter months.
