Via Instapundit and Parabolic Arc:

From Mojave, it’s a drive of nearly 50 miles through the sagebrush and Joshua trees, around dry Koehn Lake, and through the old mining towns of Randsburg and Johannesburg before you reach the unmarked dirt road leading to the site. A half mile of bad road later, you arrive at the modest but heartfelt memorial to one of America’s forgotten space heroes.

It was on this spot where [Major Michael K.] Adams and a large section of his X-15 rocket plane came to rest on Nov. 15, 1967.
