A hill located 1.1 km (3,600 feet) SSW of Obregon. NOTE: This hill is frequently stated as being located in Ogilby; however, in fact, Obregon was the closest populated place, being located on the opposite side of Obregon from Ogilby. Obregon and Ogilby are now abandoned with little to show they existed.

The hill is named for the company, Vitrefrax Corporation, that first mined there. The corporate name is derived VITREous REFRACtories as it made high temperature bricks for furnaces.
