Big Basin Redwoods State Park

Date: (Sun.) Aug. 14, 2005
Location: Boulder Creek, CA
Event Director: - 831.439.9822
Course Setters: Nick Corsano, Anneliese Steuben
Type: B; Standard 7 courses, plus Adventure Race (Long Orange) course

Sheltered by glorious redwood trees from the blazing August sun and/or inclement raindrops in the waning summer, Big Basin is an incredible place to be (and to orienteer!) — rain or shine! The first park to be dedicated in the state system, Big Basin celebrated its 100-year anniversary (as a state park) in 2002. Sold to the government by Henry L. Middleton, the park was only 3,800 acres in its infancy. Now spanning 20,000 acres, its borders range from the ocean at Waddell Creek State Beach to Castle Rock State Park, and connects via hiking trails to Skyline Drive.

On Sunday, August 14, course-setter Nick Corsano will delight intermediate and advanced orienteers with his selection of the lesser-used park area in the eastern end of Big Basin. For beginners, course-setter Anneliese Steuben will offer White and Yellow courses near the registration area, where participants can enjoy the scenery of a creek and old stands of redwoods. No one will be disappointed with the park's offerings.

Here are the mostly final course statistics:

  Course    Controls  Length   Climb   Tech. Diff.      Physical Difficulty

  AR Orange    13     4.0 km   280 m   Intermediate     Moderate
  Brown         9     2.8 km   220 m   Advanced         Moderate

  Blue         23     6.7 km   510 m   Advanced         Very Strenuous

NOTE FOR THE INTERMEDIATE AND ADVANCED COURSES: There will be a minor shuttle ride to the base of a 10-20 minute walk up to the Start. The drive is only about two miles, and not on windy roads! (The walk to the Start will be a good warm up, and the good news, of course, is that the Finish is then downhill!) If you don't want a cool-down walk back to the registration area after you've completed your course, there will also be shuttles to return you to the main parking lot.
