1561 04 May 2015 @ 1425 04 May 2015 @ 1434 Janet Jones Gizmo was erupting about every two minutes during this time for a duration of about 30 seconds each with each ending in a few seconds of steam. Sometimes "Gizmo's Pool" erupted and sometimes not. (Was there a small pool with Gizmo before??? Have to check photos on that). Yet two other times at Gizmo, no eruptions happened for the 10-15 min I was there. More to come on this on the GeyserWatch.com blog as I have time.
