The log is named after Hale D. Tharp, who was described as the first Non-Native American to enter the Giant Forest.

They climbed Moro Rock and made an encampment near Crescent Meadows.

It was not until 1869 that Tharp moved a cattle herd into the Giant Forest area.

[2] Tharp established a small summer cattle ranch at Giant Forest and used a fallen log as a cabin.

A fireplace, door and window exist at the wider end, with a small shake-covered cabin extension.
