I was with the group that headed to NY. There were 8 of us. We hit a nasty rubble band about 1/3 of the way across and two members decided to skate southeasterly back toward Charlotte because their vehicles were there. 6 of us walked/hobbled across the rubble field and continued west. As we skated Jo was in contact with Evan who indicated that a wide lead had opened more or less parallel with the NY shore and was running in a generally NW/SE direction. We skated until we saw the lead, recognized it was wider on its south end and decided to skate in a northwesterly direction paralleling the edge of the lead. Evan indicated that he and Jesse found a way across at a narrowing of the lead. We saw them, skated to them and crossed a crack dry-footed. Then, between the shore and the lead we initially portaged along the shoreline and eventually skated a narrow sidewalk south to Essex. I believe the two that turned back to Charlotte were among the five that were rescued. I think, but they would know better, that they tried to get off the plate at the place where it cracked off from the main plate body and they were left stranded on an isolated polygon between shore and the northward moving plate. I'm thankful it was large enough to hold them. It is great to say that everyone got off the ice safely and I believe there were no infractions of the Dry Foot Policy.
What happened? Yesterday we noted big leads opening up between Willsboro Point and the Vermont shore. We backed out and returned to our port in Essex. Today, with a fairly brisk south wind, temps in the 20's and alternating bright sun and cloud cover, the plate cracked off at a line generally from around the base of Willsboro Point diagonally across to Charlotte. I think that instead of just plucking polygons off the northerly edge of the plate like an off-ice wind does, the south wind moved the whole northerly end of the plate severing it on the line described above. I think the combination of open leads on the north end of the plate and the fact that the lake begins to broaden out at this point provided no restriction on ice movement so the south wind had a relatively easy time cracking off the northerly end of the plate and pushing it northward. Some folks were going to continue down to Northwest Bay to skate there this afternoon. In that situation the south wind would have a much tougher time pushing the plate because the lake narrows there at the Palisades and would serve as a choke point.
Anyway, I think that's how it all went down. Love to hear other facts and interpretations, and am very thankful all are safe.
