 Changing water level can cause sections of the ice to collapse, exposing the original ice level, creating cracks and gaps where melting can occur, and creating generally unstable ice conditions as seen here at the upper end of Wenrich Slough below Wenrich Island. Processes Observed |

At the upper end of Wenrich Slough below Wenrich Island, Sam Demientieff talks about how the channels of the Tanana River have shifted and changed the amount of water flowing into this slough. Processes Observed |

Sam Demientieff points out an air bubble in the ice at the upper end of Wenrich Slough below Wenrich Island, and talks about the thickness of the ice, the depth of the water, and how this area was open water last year. Processes Observed |

Sam Demientieff trying to figure out why there is open water in this area at the upper end of Wenrich Slough below Wenrich Island, because it is shallow and does not have the current and depth that the main channel of the Tanana River does. He discusses how the channels of the river have changed through time. Processes Observed |
 Ledge of ice that has dropped down from the river bank in the upper end of Wenrich Slough below Wenrich Island and has created a hard to see edge that could pose a travel hazard. Processes Observed |
