Is the back way in, from the Chalco side?
I have long heard of the waterfall, not sure where it is? or which route you take to encounter it? Horsey creek side?
What about the Morkill route?
Not sure the exact model number... I'll do some digging...

I bought a Mirage 20.5x8.5 and its roomy with 3 mountain sleds but can fit 4 if needed. 19' straight wall and a short v with no front door... I regret the no front door now, I thought all sleds have reverse and forgot about all of the mods and our trail/vintage junk lol
