| Comments: | aborted completely i.e. no splashing or steam jets at 1654 after playing only 7 minutes. Puffs of steam indicating that Ledge was starting to refill began at 1702 and heavy surging was noted at 1850. Observations ceased then on account of zero visibility from steam blowing snow & darkness |
