Roost of 100+ Monarch butterflies in protected area of Seminole Canyon just south of watering hole. I viewed roost the MORNING of 10/18/2015 around 10:00am. I assume they formed the previous evening. Overnight low was around
62 degrees F. by 10 am it had only warmed to around 68 degrees. Butterflies beginning to warm as sunlight began to fall within the canyon. Some were seen flying south along canyon.

Wind was from SSE and was gusting to 15-20 mph
