Around the geysers are pools of steaming water which the signs say have enough acid in them to eat through your boots.

This acidic water kills any forms of life it comes in contact with and leaves this course, white, ash like substance.

As we drove around geysers would just erupt in open areas. You could feel the heat and steam.

I took a video of Old Faithful and forgot to turn off the camera. Since it shows old Faithful for about 1 minute and my knee for another minute - I won't post it here.
