Layer: MassiveIce (ID:2)

View In: Map Viewer

Name: MassiveIce

Display Field: MassiveIce

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

This data set represents an updated Ecological Subsection Map for Northern Alaska. This update includes permafrost mapping to include the following new layers: permafrost extent, massive ice, thaw settlement potential, segregated ice and thermokarst landforms.

A prior 2014 revision focused on correcting coding errors identified in the original 2012 version. The 2012 mapping effort focused on completing the the southern NPRA, improving mapping of glacial and outwash deposits within the Brooks Foothills, and improving consistency with existing surficial and bedrock geology maps in northern Alaska.
