), causing them to drop their moisture in the form of rain or snowfall onto the Cascades. As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall. This climate supports two small glacier remnants on Gardner's northeast slope. During winter months, weather is usually cloudy, but due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer. The months July through September offer the most favorable weather for viewing or climbing this peak.

The U-shaped cross section of the river valleys is a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area.

History

Dennis Miller Bunker - Isabella Stewart Gardner - P33e6 - Isabella Stewart Gardner Museum

The mountain was named "Mt. Gardner" in 1891 by Guy Waring of Winthrop to honor

Isabella Stewart Gardner Isabella Stewart Gardner (April 14, 1840 – July 17, 1924) was an American art collector, philanthropist, and patron of the arts. She founded the Isabella Stewart Gardner Museum in Boston. Gardner possessed an energetic intellectual curiosity ...

Adventure Publications (2020), Further north, Isabella Ridge is also named after her. Waring was a friend of Isabella and he was a classmate of Isabella's brother-in-law, Joseph Gardner. In 1898 or 1899, Albert Hale Sylvester and a USGS survey party climbed the mountain. This mountain's toponym has been officially adopted by the U.S. Board on Geographic Names.
