Turtle Mountain is between Ranges 3 and 4 in Township 7, west of the 5th Meridian. It is approximately 32 km northwest of Pincher Creek and 22 km north of Castle River Provincial Park in NTS map area 82G/9.

At 4:10 a.m. on April 29, 1903, a major landslide with an estimated 30 million cubic metres of rock occurred on the east face of Turtle Mountain in southwestern Alberta, Canada. Over 70 people in the southern portion of the town of Frank were killed, and the entrance and surface workings of the Frank mine were buried. This catastrophic failure is known as the Frank Slide.
