Brief report:
This is by far the most exposed, airy and spicy 4th class route that I've soloed. A windy day on the ridge added to the alpine feeling. At one point just by the prominent notch, I thought about turning around completely. Test every hold as the rock is not 100% solid. Took the Sandia Peak tram down where a friend picked me up back to Albuquerque.
