Update 11:28AM 3/21/2026: from South Dakota Department of Public Safety “Fire activity has slowed after strong strategic efforts yesterday (3/20) and overnight.
Today federal, state and local resources continue working to secure fire lines. They are tracking down and extinguishing hot spots on the fire’s edge. Acres remain at 25 with 0% declared containment.
The goal of last nights air tanker drop of fire retardant was to help prevent any movement to the east.
A burnout operation last evening proactively eliminated available fire fuels in the area between the outer dozer fire line and the interior fire thereby creating a strong fuel break along the fire’s east edge.”
Update 8:43PM: from Qury Fire EOC “Partial Evacuations Lifted for the Sundance Fire. Mountain Lion Rd to Lone Elk remain closed. All other roads are open. THERE WILL PROBABLY NOT BE POWER.”
