Montana Tech Area

By Larry Smith
Untitled Overview of the front of Main Hall. The steps were constructed of granite and the pillars and arches were made of quartzite.

Main Hall's granite steps with dark (mafic) inclusions. This texture of dark blobs in granite is typical of many parts of the Boulder Batholith, including the Welch Quarry near Homestake Pass. Also pictured are examples from the Science & Engineering Building as well as the granite arch and rock wall at the corner of Park & Western Streets.
