Roll 6: Yellowstone: Sunset at Grassy Lake - West Thumb geyser basin - "Old Faithful" geyser
A trail to "Old Faithful" |
This is not an eruption yet - just steaming |
Everybody is waiting. The rangers can predict next "Old Faithful's" eruption to within +/- 10 minutes (and it does erupt 21-23 times a day). |
It's going... |
|
|
Full power (column height is 30-40 meters, and the eruption lasts about 1-2 minutes). |
|
|
|
The sky was cloudy and the water/steam column is not too visible. But later during the day the sun came out and there will be more pictures with blue sky |
