The brief answer is when the minor events "go real high at the same time in a sustained fashion."</span></div><div><span><br></span></div><div><span>My addition to the conversation is that this is an extremely ill-defined phenomenon. People who have seen many "locks" still miscall locks. That's just because the geyser reserves the right to do what ever it wants. The word "lock" implies that it now must erupt: clearly false. No matter what anyone says, it can look great and do nothing, or look terrible and erupt 2 minutes later. The former is much more common than the latter.</span></div><div><span><br></span></div><div><span>To greatly summarize a large body of empirical experience, when people have been
excited about F&M, you want to be there by about 10 min. after Gold starts. If I'm there, you can join me watching it not erupt.</span></div><div><br></div><div style="font-size: 12pt; font-family: 'times new roman', 'new york', times, serif; "><div style="font-size: 12pt; font-family: 'times new roman', 'new york', times, serif; "><font size="2" face="Arial"><hr size="1"><b><span style="font-weight:bold;">From:</span></b> Bob Mabery <bmabery@gmail.com><br><b><span style="font-weight: bold;">To:</span></b> geysers@lists.wallawalla.edu<br><b><span style="font-weight: bold;">Sent:</span></b> Thursday, August 18, 2011 3:37 PM<br><b><span style="font-weight: bold;">Subject:</span></b> [Geysers] F&M - What's a "Lock"?<br></font><br><div id="yiv948721369">I read with interest the detailed descriptions of the varied cycles of Fan and Mortar.<div>Is there someplace that I can read a definition of the elements of the cycle, perhaps with
