Seems like my brother and I might be a little late on piccking up planning for this trip but I was hoping someone could point me towards some good info/breakdown of how to go about planing for a Cross-Canyon hike (would love to do down-up, down-up but open to other suggestions). Need some ideas on routes, permits to get, estimate on time and if weather may be a big factor. Thanks also if you think we are to late for permits and campsite reservations than ideas for other adventures in the Vegas/Salt Lake/Northern AZ area would be great. The dates are between 16-25 around 5-8 days. Thanks look forward to your sage advice.
