- The limestone cliffs of the 760-acre Trombetta Canyon NAP provide habitat for two rare plant species, yellow mountain avens and Steller’s rockbrake. The site includes extensive scrub-shrub and emergent wetlands at its lower end, providing habitat for a third rare plant, sage willow. Trombetta Canyon is isolated from disturbance by its location and topography, and offers protected habitat for a variety of other organisms-particularly those that may be adapted to limestone substrates.

Michelson’s wonder was what his head did with his hands, and a few boxes and rotating mirrors. He measured things, especially things that were regarded as unmeasurable, ineffable, and precious as life itself. Among other things, he had measured light and a star. I watched him play billiards nearly every noon for several months before he retired from the University, and, in introducing myself, I could further say with equal truth, “Shake the hand that shook the hand of John L. Sullivan.” If I get the right opening, though, I prefer saying, “When young, I watched Michelson play billiards.”
