What are the names the pioneers gave to The Three Sisters?

The Three Sisters are located in the Cascade mountains of the state of Oregon, in the United States.

The North Sister, also known as "Faith", is the oldest and most highly eroded of the three, with zigzagging rock pinnacles between glaciers. Faith is 5 miles (8 km) wide, and its summit elevation is 10,090 feet (3,075 m).

The Middle Sister, also known as "Hope". She has an elevation of 10,052 feet (3,064 m) and is cone-shaped. The eastern side has been heavily eroded by glaciation, while the western face is mostly intact. Of the Three Sisters, Middle Sister has the largest ice cover.

South Sister, also known as "Charity", is the tallest volcano of the trio, standing at 10,363 feet (3,159 m). South Sister has an uneroded summit crater about 0.25 mi (0.40 km) in diameter that holds a small crater lake known as Teardrop Pool, the highest lake in Oregon.

The three mountains have their own individual geology and eruptive history. Neither North Sister nor Middle Sister has erupted in the last 14,000 years, and it is considered unlikely that either will ever erupt again. South Sister last erupted about 2,000 years ago and could erupt in the future. After satellite imagery detected tectonic uplift near South Sister in 2000, the United States Geological Survey improved monitoring in the immediate area.
