Yosemite Daily Report: 

Yosemite Daily Photo, Muddy Merced River 12/3/14

We finally got enough rain to get some flow going in the Merced River on 12/2 & 3. This is mud and silt that has flowed in from the El Portal and Dog Rock fires from this summer. We are very lucky as this rain was on and off, had it been steady we could have had mud slides.

Yosemite Daily Report: 

Yosemite Daily Photo, Old Trail up Rattle Snake Ridge, El Portal Burn Area, 11/29/14

Since the El Portal Fire of 7/14 we have noticed a old trail that has become exposed on the ridge, RattleSnake Ridge, on the east side of Crane Creek just up from El Portal. It appears to be very old and graded for horses. Today I found it and hiked up it to where it meets the power line that runs from El Portal to Foresta. I then hiked down the power line trail which is just east of this old trail and much steeper.

This area is devastated by the fire with mini debris flows evident from the last light rain we got. If this area gets a heavy rain there could be debris flows.
