Below is my transcription of the NRE summit register. It was immensely fun to do this, read all the entries from climbers past, learn about new routes. It sure has me psyched to get back up there and climb more. Also I'm now eager to get my hands on the other summit registers and sift through them.
I did my best to record all the original entries, but some pages are badly torn, weathered, or simply hard to read. I noted this in [brackets] in most places. I think I'll print this entire register out on sturdy paper and replace it back with the summit register so that others can read the history. I also will try to archive the originals (and original copy since the 1954-1969 entries were already re-copied once) at NMSU or some other local archive. Finally, the left-hand column estimates the Recorded Summit Ascent # by ascent party. It is approximate, especially in the later decades of the register as pages may have been lost, etc.. By this approximation, our last ascent was the 159th.
