[2] Before the Palmer chairlift was constructed in 1983 (which provides access above the 7,000-foot (2,100 m) level), the conditions at Timberline allowed skiing from the Mile November through July or August.

Ski and snowboard camps draw thousands of people to the slopes during the months of June, July and August.

The current Palmer chairlift was completed in 1996, and is built to withstand wind gusts of over 100 miles per hour (160 km/h) and 200 inches (510 cm) of snow.

Its construction time was less than six months due to a limited building season imposed by the local weather conditions.

[4] The Jeff Flood Express detachable high speed quad chair opened for the 2007-2008 ski season.

Thanks to the added terrain accessible from Jeff Flood, if the Palmer lift is open, it is possible to ski a non-stop run over 3.5 miles (5.6 km) in length with elevation change of about 4,000 feet (1,200 m).

[8] Skiers, snowboarders, and sightseers ride up the Magic Mile chairlift to the Palmer Glacier and its lift, where most of the summer skiing takes place, particularly later in the season.

After approximately mid-June, it is necessary to walk at least part of the way to reload the Magic Mile, and feasible to ski to within a few hundred feet of the parking lot until mid-August.

On warm days, most skiers leave by late morning due to soft and wet snow conditions.
