The mountain was formerly known as Mount Pulgar, a name it acquired during the Spanish Colonial period. Pulgar, means thumb in Spanish, and the name was probably translated directly to English following the ousting of Spain during the Spanish–American War. The name may have arisen as a result of the mountain's profile, which vaguely resembles the tip of a thumb protruding from a clenched fist.

The upper reaches of Thumb Peak are populated by species associated with ultramafic soils, including a number of endemics, such as the tropical pitcher plant Nepenthes deaniana, rediscovered on the mountain in 2007 for the first time since its description in 1908.[2][3]
