Menu of courses: Short white, white, yellow, and orange only. No need to register online. Please notify the registrar, Eva Ruutopold, of your course choices and also your SI stick number, if you have one, so that we may gather an accurate count of maps to be printed for both days.

The Boulder Dash is a 2-day cumulative time classic event sanctioned by Orienteering USA, open to all age groups and classes. It is a National Ranking Event and we will offer a complete slate of courses for everyone from M/F 10+ to M/F 90+.  Non-US citizens and residents are welcome and encouraged to compete.

For those looking for less competitive races, we will offer a parallel recreational event both days with White, Yellow, and Orange courses.  These beginner to intermediate level courses are open to groups as well as individuals.  The recreational courses do not require pre-registration, and instruction will be provided.
