Glacier Point

Its glacial origin is definitely proved by the presence in it of rocks derived from Little Yosemite Valley and the Sierra Nevada.

This steep, rugged path became known as the Four Mile Trail, which was completed in 1872, allowing visitors to hike to the summit for sweeping views of Yosemite Valley.

[5] By the early 1900s, the road was improved for automobiles, allowing easier access for visitors with a direct, drivable route to the point.

The federal government took control of the road in 1917, the same year the Glacier Point Hotel opened.

Note, however, that the trail can be extremely hazardous when covered with snow or ice, so it is usually closed by the Park Service from December through May.
