CACTUS

CACTUS was a ground-based telescope outside Daggett, near Barstow, CA, close to the old road. It began life as a solar power station known as Solar Two and was converted into an observatory starting in 2001. It ran only briefly before funding ended, and the facility was demolished in 2009. Nothing remains to visit, but the story is a curious footnote on the desert stretch near Barstow.

What is CACTUS?

The letters of its name spelled out what it was: a converted atmospheric Cherenkov telescope built from Solar-2. Its first observations came in fall 2004, and its last runs took place in November 2005, when National Science Foundation money ran out. The University of California, Davis operated it, and Southern California Edison owned the site.

Visiting CACTUS: tips

The telescope is gone, so there is no site to tour. Liberty Sculpture Park is about 2.5 miles away and Calico about 5.6 miles off.
