Trek Highlights

No disrespect here, but the real reason this mountain is named Mt. Hillyer is because it is more of a hill than a mountain. From Rosenita Saddle to the top, it is a leisurely stroll past purple, yellow, red, and blue wildflowers. The trail meanders past lovely grasslands and then dashes up for a brief moment. The summit plateau is covered with a bunch of rock piles, one of which presumably contains the highpoint.

Tiburcio Vásquez was a horse rustler who stashed horses at Horse Flats by Chilao. His nickname was Chillia, hot stuff, for killing a bear using only a knife. He set up a hideout among the boulders at the top.
