Sunset as seen through the smoke of a prescribed burn in the Jemez Mountains, New Mexico. The burn was conducted to restore fire as an ecosystem process and reduce hazardous tree densities and fuel loads due to more than 100 years of fire suppression. Foreground trees (Douglas-fir and aspen) were killed during the Cerro Grande fire in 2000.

This Riffle is caused by the Paira River colliding with the Colorado River. Usually, there are two distinct colours — crystal blue from the Colorado and a murky brown from the sediment filled Paria.
