I suspect this is P. tescamnis, which named after the corresponding FNA volume came out. The flowers look more yellowish and smaller than sparsiflora which has a wide column. Also the upper sepals look like they are forming a hood more like tescamnis, and the leaves are mainly basal. While sparsiflora is variable, it is usually more leafy than this (see also the FNA drawing). Another factor is that the flora of Red Butte Canyon has been fairly thoroughly studied and while it certainly could have been missed as with a few other species, sparsiflora has not previously been identified as occurring in the canyon (although it is here in the general area and in SL County). Without being able to see the details of the flower, it is difficult to be sure.
