The season
What fills Roughlock Falls, and when
Little Spearfish Creek runs on Black Hills limestone groundwater topped with snowmelt, so Roughlock keeps its terraced flow through every season; the gauge a mile upstream reads it live. South Dakota Game, Fish and Parks manages the nature area, and its winter note matters: the access road closes for snowmobile season while the lodge trail stays open.
What the agency itself says
Spearfish Canyon Nature Area includes the Roughlock Falls, Spearfish Falls, and the Savoy Pond area. The canyon is considered one of the most beautiful locations in the Black Hills. A trail system connects all three areas and offers spectacular views of the waterfalls and foliage in the fall.
