Two women were taken to the hospital after rolling their minivan Tuesday night.
Officers on the scene say two women aged 27 and 65 were traveling southbound on Bunker Road in North Rapid City.
They say the women were driving too fast on the dirt road and lost control.
The van landed upside-down against a utility pole in the front yard of a mobile home lot.
They were taken to Rapid City Regional Hospital with non-life threatening injuries.
Officers say alcohol was a factor in the crash.
