Natural Bridges - Sipapu Bridge
Detailed Description
This view is looking upstream toward Sipapu Bridge. The erosional forces that sculpted the natural bridge gave it a natural stable arch geometry. This great size and span of the arch suggests that it took many thousands of years for it to reach its current appearance (Huntoon and others, 2000). The bridge itself consists of a massive tightly cemented layer of sandstone. This view shows the broad, upper valley surface across which the ancient meandering stream of White Creek Valley flowed before the modern period of stream incision began.
