Come out and join us for a cool Sunday morning of Classic-O courses on Mt. Lemmon (Bigelow)!  Up at 9,000', temperatures are typically 20-30 degrees cooler than down in Tucson, so it should be a pleasant 75 degrees during the day.

Courses: Three courses will be offered:  Short, Medium and Long.  The Short course will be 2.3km long with about 100m of climb.  This will be a white/yellow level course, staying along trails, roads and other linear features.  The Medium course will be 3.9km long with about 185m of climb.  The Medium course will be an orange level course, allowing you to venture off the trails and roads.  Finally, the Long Course will be 5.9km with 300m of climb and will be a green/red level course.  The elevation and terrain will combine to make these courses, especially the Medium and Long courses, more physically challenging than usual.  Because the Bear Wallow map is centered on the ridgeline leading up to Mount Bigelow, there will be many opportunities to practice your contouring.  Adding to the challenge is the abundance of pine needles carpeting the forest floor which makes the traction tricky, but does help pad any unanticipated falls!

There will be one water control on the Medium and Long courses.  There will be some water at the start/finish/registration area, but since there is no water on Mount Bigelow, please bring a little more than you think you will consume.

Large Groups:  If you are planning to bring a large group of more than five people, please let the course setter Jeff Coker (uwviper (-at-) aol (-dot-) com) or meet director Mike Thompson (oclubmike (-at-) gmail (-dot-) com) know so that we can reserve enough maps for you.

Youth Groups: All participants under 18 must provide a waiver signed by a parent or legal guardian.  If your group plans to bring a minor without their parent/guardian, then please download a copy of the Waiver and Permission to Participate form from our Documents, Guides, and Forms page (look for it under the "For Orienteers" section) and have it completed and signed by a parent/guardian before you bring it with you to the event.  For more details, see our article about the waiver form for minors.

Directions:  The GPS coordinates for start/finish are 32.416695 -110.733862.  From Tucson, take the Catalina Highway approximately 21 miles to Mt. Bigelow Road, about a mile past Palisades Ranger Station.  Turn right on Mt. Bigelow Road and look for orienteering signs.  Park here on the side of the road.  You will then walk about 200m up the road to the first junction, near the observatory entrance.  Turn left and proceed gently downhill about 300m to the start location where there is a junction of trails and a wide clearing.  It takes about 75 minutes to get to the event site from downtown Tucson.

The meet directors are Alexis Mills and Mike & Valery Thompson.   Contact Mike at oclubmike (-at-) gmail (-dot-) com if you have questions about this meet or would like to help out.  Please offer to help out with registration, timing, or control retrieval.  The fees collected at each event only cover the costs for permits, insurance, transportation, map printing, supplies, and equipment used at the event.  They don’t cover planning, organizing, or running the event.   It is only through the generous volunteer effort of us club members by which these events can happen!
