I never had a snorkel before this run, and I had run much deeper/faster water. That doesn't mean I didn't want one. My air cleaner was fairly high in the engine compartment, and if I maintained the air pocket and kept a fairly steady speed I never got water near the filter. However, there were times...
We actually turned around in the middle of the first major bog, realizing that it would take many, many hours to get past the remaining bogs. As it turned out, we spent 4 hours getting back to the trailhead from that point, and speeds on the easier parts were much higher than they were coming in.
Purches is one of my favorite trails up here, combining rocks, hillclimbs, mud, and water crossings in a loop that can be run in one looooong day or two manageable days. Since time was compressed between the wedding and Scott's departure that night, we limited the number and types of rigs and tried to get as much done as possible.
I had just pulled the Jeep out of long-term storage and made a few modifications to improve capability and durability. Unfortunately, I didn't drain the fuel tank well enough, and silt clogged my fuel filter periodically, making sustained high RPMs pretty difficult. Fortunately I had a clear glass pre-filter installed to tune in my fuel pressure, so clearing the silt wasn't too painful.
Since I hadn't wheeled in years, my skills were somewhat diminished. Something to be said for remembering exactly what your vehicle is capable of. The main thing I (re)learned was that rigs on 33s shouldn't follow the tracks of rigs on 37s into mud holes.
Lots of fun to get out there and get a little dirty. Must do it again...
