Passing through Tracy Arm - Seeing the Sawyer Glacier
In recent geological times, (within the last 400 years) a glacier sat at the mouth of Tracy Arm depositing large amounts of gravel and rock producing a recessional moraine bar which can be seen at low tide. The flood and ebb tidal currents in and out of Tracy Arm have carved a narrow opening through which the ship needs to navigate. Once across the bar the water depths increase rapidly to over 1000 feet. The tremendously steep fjord walls , hanging valleys, waterfalls and glacially polished rocks all contribute to the great experience that waits us in Tracy Arm.
The Glacier is called the Sawyer Glacier.
