Horseshoe Lake is located in the southeast portion of Lassen Volcanic National Park. It is approximately a mile and a half northwest of Juniper Lake. It was originally known as Grassy Lake, but no doubt after the creation of the park, someone wanted to give it a more colorful name. In the1890s Adolph and Anna Olson had a squatter’s claim and for nearly twenty years used the area for summer livestock grazing. Jakey Lake located northeast of Juniper Lake was named for their son, Jakey Olson who died at the age of seventeen.
