While it wasn’t a particularly hot day, Big Bear’s density altitude was reported as 8,200 feet, resulting in a higher true airspeed compared to indicated airspeed. Increasing true airspeed makes the turn radius wider, resulting in an overshoot. And it’s all so much harder in turbulence.

However, at 5:36:23 he still had an altitude of 7025 ft MSL, i.e. a normally very “safe” pattern altitude of almost 1500 ft, and prudently began to head toward the east end of the runway. 65 kts IAS given the high density altitude. 16 seconds later, at 5:36:39 the sink rate diminished to 273 fpm.
