REVISION DATE: 2/21/2022

Overview: 

Box Canyon, located 45 minutes south of Tucson on the west side of the Santa Rita mountains, is a north-south oriented mountain range that offers excellent XC potential, and also produces great glass-off flights and year-round flying. There are multiple launches, serving multiple wind directions, wing types, and hiking desires.

Only 8-10 miles south of the Box launches are Madera Canyon and Mt. Wrightson (9,452’). A world-renowned location for bird watching, Madera Canyon is a major resting place for migrating species, while the extensive trail system of the Santa Rita Mountains is easily accessed from the canyon’s campground and picnic areas.

Mt. Wrightson was named for William Wrightson, a miner and entrepreneur. The peak’s distinctive pyramid-shaped profile is visible from much of southeastern Arizona and adjoining areas in Sonora, Mexico.

Site Requirements

  • Current SAHGA (or AZHPA) and USHPA memberships.
  • All visiting Pilots are required to have a site briefing prior to flying

Skill Requirements

  • For Glass-off: P2 w/ RS

  • For Mid-day: P2+ RS, XC, TUR, RLF

General Rules

  • All Box Canyon launches sit on USFS land, and the LZ sits on the Eastern edge of the University of Arizona Santa Rita Experimental Range (SRER). Pilots are reminded to be a good stewards of the site to ensure future access.

Know Before You Go

  • Using the provided images, familiarize yourself with the details and potential hazards of the site.
  • Rocks, shrubs, and cactus below each launch present potential hazards in weak winds.

  • Be aware of the forecasted changes of wind direction and conditions
  • Rattlesnakes are often encountered on the trail and on launch. Proceed with caution.
  • Lower launch sits on a hill that protrudes from Alazurra Peak and has 3 takeoff directions. Because of its shape, the wind direction sometimes varies depending on where you are standing on it. (See images for more precise information.) Take the time to observe multiple wind indicators before deciding which launch to use.

Flying

From Lower Launch

  • During evening glass offs, the generally followed flight plan is to bench up towards Alazurra Peak via the E-W ridge created by the peak and Lower Launch.
  • Lower launch is ~800’ above the LZ. Head for the LZ once you are flying below launch to avoid coming up short and landing in the bushes or wash.

From Mid Launch

  • Follow the terrain from launch to the LZ.
  • With NNW winds, it is best to follow the large E-W ridge to the left (south) of launch.
  • With W winds, the smaller ridge to the right (north) of launch is usually a better choice.

From Top Launch

  • From this launch, it is usually easy to follow the main ridge leading from the top of the mountain down to the lower launches.
  • Stay on the windward side of the ridge, even if you are above it.

Approaching the LZ

  • Once you have cleared the wash, 1,000’ east of the LZ, there are plenty of places to land.
  • Plan to arrive high enough to fly a rectangular pattern around the LZ to observe the wind and thermal conditions.
  • When landing East to West, plan to land East (short) of the center of the LZ (windsock), as a barbed wire fence is only 300’ West of the center of the LZ.
