[Geysers] small geyser below Marmot Cave

[Debbie Sjodin]

I was intrigued with the small feature below Marmot Cave and since I was
having a problem with my bad knee I decided to observe this feature for a
while.

These are my conclusions after 7 or 8 non-continuous hours of observation.

These observations were valid for August 3-6, 2009

It is a geyser

It is not erupting for more time than it erupts.

 

Assumption: An eruption is when water is fairly consistently being splashed
beyond the inner rim of the crater. Breaks in the splashing not lasting
longer than 15 seconds do not make a separate eruption

 

It has 2 types of eruptions

 

One type of eruption is usually 5 minutes or less, often 2 minutes or less
and does not send water down the runoff channel.

The other type of eruption usually lasts 8 to 15 minutes and does produce a
stream of water down the runoff channel.

These types of eruptions sometimes alternate but there can be strings of the
shorter eruptions without one of the longer ones.

 

Because it nearly continuously chatters I call it the Mouth geyser.
