There's a good, signed, clipped trail from the west. The west ridge was pretty straightforward, with the final move more like 4th class IMHO. Traversing on to the Nesakwatch Spires was considerably trickier, involving a tunnel getting into the notch between Rexford and the South Spire. I wasn't up to doing the off-width on the summit block. Getting to the saddle between the spires was probably low 5th with a bit of tricky route-finding. Fun day.
Nice trip, did it as an overnighter and took 9 T3's and 12 IB Profen to keep the back pain away from a near fatal avalanche just a few months prior. This was my first descent size peak since that accident that broke my leg. We also did the easier of the two Nesekawtch spires. Also did it as a day trip the summer before and would like to do a more tcehnical route from the other side in the future
Curt and I summited Rexford after doing the Ensakwatch Enchainment. Overall this a fun linkup with lots of ground to cover and great views all day. Not a classic, but worth doing nonetheless. It took us 9 hours camp to camp belaying nearly every 5th class pitch and even some 4th class. Can be done car to car comfortably by a fit party.
