mpson Firehole River 229 Yellowstone May 29, 1932 than the same deer which congregate around Mammoth. No bears nor bear tracks were seen this entire day. We caught 6 trout between 8 and 10 inches long in the Firehole; 3 were Lack Sever, 2 Eastern Brook, 1 Rainbow, all in good condition. Many people were fishing all along the Firehole, but so far as we could ascertain, fish were caught with spinners, or wet flies. The water surface was swarming with May flies but no fish were jumping. Consequently our dry flies were not taken. As we returned past Sunger Peak and through the Hoopbox we watched an aurora borealis. It was not very bright but was exceedingly beautiful & fantastic. At its brightest it cast a weird luminous glow along the side of Sanger Peak.
