In the summer of 1891 it was the privilege of the writer to visit what is known as Topaz Mountain in southern Utah. It is about thirty-five miles south of the northern end of the Dugway Mountains, called by Simpson the Thomas Range, twenty-five miles northwest of Deseret, forty miles north of Sevier Lake, and about the same distance west of Eureka, Utah.
