Historical & Ecological Origin

Glassford Hill is an intrusive igneous body, primarily composed of granite, formed during the Laramide orogeny approximately 70 million years ago. Its current form is the result of millions of years of erosion. Historically, the hill was a significant landmark for indigenous peoples and later for early settlers in the Prescott area.
