Greetings, I've been itching to do this loop in the Marble Canyon area for a long time and I have collected any possible beta to make it a successful trip (Todd Martin & George Steck to be precise). I wanted to inquire any info from fellow canyoneers and grand canyon addicts if they have any tidbits to assist me. I know there is the route along the river to Rider from North if the Colorado is "low" which requires a wade through stagnant water as specified by Todd Martin and then there is the high route that bypasses this section which is surely to be loose and exposed. My questions are... 1) Anyone reading this ever done any of these routes and have any recommendations? 2) What cfs level is the Colorado considered to be low? I'm aiming to do this in late March if anyone else is curious as I am about this loop. Thank you for reading.
