3 years of phase-out (Table 7). Thus, from 1959 through 1967 an average of<br />

six grizzlies became campground foraging bears each year, but during the<br />

rapid cut-back in garbage (1968 through 1970), an average of 23 grizzlies became<br />

campground oriented each year. Data in Table 7 also show that Grant<br />

Village, which was first opened to the public in 1967, presumably had no problem<br />

bears that year, as none were captured. The following years it was visited<br />

by grizzlies. Twenty-five were captured during the three-year period of revised<br />

management. Similarly, no grizzlies were captured at Slough Creek, Tower<br />

*Canyon Village includes—Canyon Village and Otter Creek Campgrounds. Lake<br />

includes—Lake, Fishing Bridge, Bridge Bay and Pelican Creek Campgrounds.<br />

Grant Village opened in 1967 when the National Park Service began phasing<br />

out open-pit dumps.<br />

†Unmarked grizzly bears entering campgrounds during 1968 and 1969 could not<br />

be individually marked because of Park Service policy prohibiting marking of<br />

any animals in Yellowstone. Thus, in addition to marked animals, a minimum<br />

number of unmarked individuals, determined by criteria of sex, age and time<br />

of capture were recorded for this period.<br />

‡ In 16 instances, bears were captured in two areas during a year. The corrected<br />

total of individual grizzlies captured per year corrects for this bias.<br />
