In recent geologic 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 tides. The ebb flood of water into Tracy Arm has carved a narrow opening which our ship sailed through. Once we went inside the bar, the water depths increase rapidly to over 1000 feet. The tremendous steep fjord walls, hanging valleys, waterfalls and glacially polished rocks are quite a sight to see. (Princess Patter)
