As the oldest settlement on Lake Tahoe, Glenbrook played a significant share of Nevada’s statehood as the main supplier of timber to the Comstock Lode and Virginia City. The first settlers of the valley, which included Captain Augustus W. Pray, arrived in 1860. Pray built a sawmill in 1861. The community took its name from the former “Glenbrook House hotel”, which in face was named after two primary local geographic features — Glen, a secluded valley, and Brook, a small stream. From forested areas close the lake, logs were driven by the side of stream or barged to Glenbrook mills. In 1875, the town had four sawmills, a store, bowling alley and billiard hall, two hotels. After 1880, logging upheaval was in halt and was isolated by the stop of the century.
