Alfred Hulse Brooks (July 18, 1871 – November 22, 1924) was an American geologist who served as chief geologist for Alaska for the United States Geological Survey from 1903 to 1924.

[4] In 1898, the federal government announced a systematic topographic and geologic survey of Alaska that would include renewed exploration of what became known as the Brooks Range.

Alfred Hulse Brooks, the new assistant geologist and head of the Alaskan branch of the United States Geological Survey (USGS), called the project "far more important than any previously done," due in large part because it "furnished the first clue to the geography and geology of the part of Alaska north of the Yukon Basin."

Between 1899 and 1911, six major reconnaissance expeditions traversed the mountain range, mapping its topography and geology and defining the patterns of economic geology so important to prospectors and miners.

[4] Every year from 1904 to 1916 and from 1919 to 1923, Brooks wrote summaries of Alaska's mineral industries.
