News article included with the image reads: ""BLAZE AT DAM CONSUMES SIX HOMES TODAY -- Six families at the river landing are without homes and belongings as a result of a brush fire which started about 10 o'clock this morning. While the fire was soon under control the flames during the blaze were at times 50 feet high, fanned by a high wind which rushed down the canyon. Sergeat Clyatt, a one time cook at a military school in the east, who had a bakeshop at the landing, was also burned out, but as he still had his oven, and he had his dough ready for baking, he established a relief station immediately and at last reports was serving bread and coffee to the homeless families. -- LAS VEGAS EVENING REVIEW JOURNAL, March 28, 1931, p. 1, col. 6.""
