Everts. and Gardiner areas. Woodring thought that Skinner's count was high. Had reason to believe there were a few others in Geode Cr.-Oxbow Cr. area. One day count by 3 men. Those outside park were just below Stoll's Ranch but not yet down to Hoppe's Placc. Thought the count was not complete. Five died during the winter leaving 320. About 65% of the herd are males. Census was a "full count. It Other counts: January-416, March-384, April-498. Other counts: January-S44, April-363. Low count, by no means representative of the actual numbers. Incomplete count. Data source" Count by 7 men considered not fully successful. Unsuccessful 18 count also tried March 19. Mammoth area-4, Mt. Everts-84, Gardiner-Reese Cr.-41S (for total of 503). Count by 10 men was one of the most accurate and complete ever 19 taken. Increase over last year reflects better count rather than actual increase. Count by areas was: Reese Cr.-Gardiner-446, Mt. Everts-Sl, Mammoth-O. Six men, excellent weather, thorough coverage of counting units. 20 Outside count by Forest Service. Antelope are increasing. Count by area: Reese-Cr.-Gardiner-S04. Gardiner-i30, Mt. Everts-152, Mammoth-D. Park count by 12 men. excellent weather. but animals widely 21 scattered which might account for lower count than year before. Outside count by Forest Service. Count by area: Reese Cr. Gardiner-347. Gardiner- 210. Mt. Everts-103. Mammoth-2. Beattie Gulch-88. Pronghorn, deer. sheep counted separately for first time and may 22 have increased count accuracy. Nonnal to mild winter. Includes 70 reported by Forest Service and ranches near Corwin Springs which wasn't covered. 7 8 9 10 11 12 13 14 14 15 16 17 17 17
