I have seen Shell Spring quiet for ~20 minutes on a couple of occasions when I was cleaning at Biscuit Basin. I did not time the cycle lengths, however. Last Friday I saw Silver Globe Slit to 8-10 feet, again while cleaning. East Mustard Spring is also active with intervals about 6 minutes.

It is capable of 10-15 feet, so this activity is clearly anemic. Jeff Cross Jeff.cross at wallawalla.edu -------------- next part -------------- An HTML attachment was scrubbed...
