Trinity, East Fork

Upper EF Trinity above mumbo creek confluence: Tyler Pohle, Dustin Knapp, Ben Koerber, Adler Thomas, Jared Sandeen and myself did this trip on 6/2/23. The flow on the Trinity above Coffee Creek was 1600 dropping to 1400. Ben had walked the river the previous summer and thought it would be a cool add on to the Regular EF Trinity from Mumbo Creek to the reservoir. We drove roughly 3 miles east upstream from the usual put-in at the bridge above Mumbo Creek confluence. We walked down to the river where there seems to be a soda spring and creates a broad opening that was easy to walk. The flow was low but seemed floatable and sufficient for a creek that steep. I think a little more water would have been nice but it could quickly become to high. The riverbed is narrow but channelized in many small gorges and pinches. We leap frogged while scouting which there was a lot of. The continuous nature requires a lot of scouting ahead because its hard to stop. Scout all blind corners and drops. There are several great boofs and pinch moves. We had one pin that was touch and go for a minute and required a z-drag but ended well. It took us 5 hours to go 2.5/3 miles. What we intended to be an add on became our whole day so we took out at Mumbo Creek. This section is steep and blind but worth doing if you like a little punishment and solving problems. Class V. At the time of this writing there is a huge tree blocking the road on river left from take-out. The alternate rd to Ramshorn, which is shorter and faster.
