The now 100%-contained Las Conchas Fire transformed the Jemez Mountains’ normally clear and sparkling Valles Caldera-draining rivers into dark, ashy, and muddy waterways this weekend.
The San Antonio River was black on Saturday, and a witness stated that the creek “smelled like ash…like when you douse a fire with water.”
The Jemez’ second caldera-draining river, the East Fork of the Jemez River, did not emit such an aroma this weekend, but it was also much darker than usual. On Sunday, I walked from the home of VallesCaldera.com to the East Fork Box, and despite the dirty state of the river, I submerged myself in its cold waters for the first time since before the Las Conchas Fire ignited, which served as a joyful and refreshing homecoming to a river that had been off limits during this intense crisis.
The San Antonio rises in the charred Valle Toledo, while the East Fork’s headwaters are located on the far eastern side of the Valle Grande (which also burned). The confluence of both rivers can be seen at the tip of Battleship Rock, where the streams form the Jemez River (you can download a 360° panorama from the top of Battleship Rock here, and view all the rest of our panoramas here).
Below are a couple of photos of a darkened East Fork of the Jemez River running through the East Fork Box yesterday.
John Fleck of the Albuquerque Journal wrote an article Saturday on the impact of the fire on the watersheds of the Jemez Mountains. In the story, Fleck describes how ashy and muddy conditions in the Rio Grande (into which the Jemez’ streams flow) caused the city of Albuquerque to temporarily cease pumping water from the river for its drinking water last week. However, the city resumed diverting water from the Rio on Friday.
As an aside, the song “Black Muddy River,” by a well-known band from San Francisco, seems very appropriate for the state of the rivers that drain our sacred caldera. Click here to listen to the tune.
When the last bolt of sunshine hits the mountain
And the stars start to splatter in the sky
When the moon splits the southwest horizon
With the scream of an eagle on the fly
I will walk alone by the black muddy river
And listen to the ripples as they moan
I will walk alone by the black muddy river
And sing me a song of my own
