The Sentinel is a 7,120+ ft (2,170+ m) elevation Navajo Sandstone summit located near the Court of the Patriarchs in Zion National Park, in Washington County of southwest Utah, United States, that is part of the Towers of the Virgin.

It is set alongside the North Fork of the Virgin River which drains precipitation runoff from this mountain.

[3] In 1995, a landslide at the base of The Sentinel dammed the Virgin River and washed out a section of the park road.

According to the Köppen climate classification system, it is located in a Cold semi-arid climate zone, which is defined by the coldest month having an average mean temperature below 32 °F (0 °C), and at least 50% of the total annual precipitation being received during the spring and summer.

This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
