State police at Frackville reported investigating a one-vehicle crash about 10:35 p.m. on Wednesday, Aug. 1, along SR339 in East Union Township.
Troopers said Heather Hallidin, 44, of Eagleville, Montgomery County, was southbound and rounding a right-hand curve when she was unable to avoid striking a boulder in the southbound lane of travel.
Hallidin lost control of the vehicle causing it to roll over counter-clockwise onto its roof, coming to rest blocking the southbound lane.
Hallidin and her daughter, 8, and son, 10, were not injured.
Another passenger, an 11-year-old male from Norristown, complained of neck pain and was taken to the Schuylkill Medical Center-S. Jackson St., Pottsville, and later released to his parents.
