This article draws from and builds on two posts on the UCAR online AtmosNews website (https://www2.x.edu/atmosnews/opinion/4616/cloud-remember-part-2-mystery-solved and https://www2.ucar.edu/atmosnews/opinion/4209/cloud-remember-and-mystery-solve). In addition to the people mentioned in the text and captions, many others contributed to the discussion on this cloud. In addition to those mentioned in the narrative, Jielun Sun (NCAR) referred us to datasets we were unfamiliar with, and Alan Scott Kittleman (University of Colorado) educated us about the contents of the CU Atmospheric Observatory website. We wish to acknowledge our internal reviewers, as well as Tammy Weckwerth (NCAR) and an anonymous reviewer for improving the paper through the formal review process. Two of the authors (Schlatter and LeMone) have modest postretirement support from their respective employers, NOAA and NCAR. Henson is supported by UCAR. NCAR and UCAR are supported by the National Science Foundation.

2 In LeMone's first calculations using the original cropped photo, the reference point was a rock outcrop slightly more than halfway between the two trees and the top of the ridge in the two pictures in Fig. 3, and a range of photo locations was used. The earlier “most probable location” of LeMone's photo was not far from the actual location. Use of the two trees and the correct location increased the cloud-height estimate only slightly compared to the first result with the best location, so the more recent calculation using Fig. 3a is highlighted for brevity.
