It was uploaded to YouTube by Kevin Osborne. From the description there:
In this video, tanker 910 is dropping on the west flank of the Goff Fire (part of the Fort Complex) in late summer of 2012. The video was taken from Tim’s Peak, north of Hwy 96 on the Happy Camp/Oak Knoll District of the Klamath National Forest.
Also, check out these very impressive photos taken by Michael Meadows of the DC-10 dropping on the Powerhouse fire north of Los Angeles June 2, 2013.
