description Ellsworth Esker Overview
The Ellsworth Esker is a prominent glacial landform located in Hancock County, Maine. Formed by the deposition of stratified sand and gravel within a subglacial river tunnel during the last ice age, the ridge runs roughly north to south through the region. Because it provides a continuous stretch of elevated, well-drained terrain in an otherwise uneven landscape, the esker has historically been utilized for road construction and natural drainage pathways. It remains a visible geological feature influencing the local topography.
