The most famous geyser in the park , and perhaps the world , is old faithful geyser , located in upper geyser basin .
黄石公园或许全世界最著名的间歇喷泉是位于间歇喷泉盆地上游的老忠实间歇喷泉。
When it erupts , droplets spray for yards around ( watch out for your cars , glasses and camera lenses ) , helping build the orange-red mineral dome that circles the geyser .
When the geyser is quiescent , the wet dome-top is peaceful and cool enough that flocks of birds , such as pigeons , land on it to check out the possibilities .
Her examination of a grass species growing in the hot and hostile environment of a geyser field in yellowstone park showed that its heat tolerance was conferred by a virus that lives in a fungus which is , itself , symbiotic with the grass : no virus , no heat tolerance .
