Description:

Abstract:

Mineral exploration activities included measuring gravity variations using the Bouguer (Boo-gay) scale. These values were mapped by CSD geologists (mainly Ray Burchett) from a series of data sites roughly one per township for eastern and southern Nebraska. Data for the panhandle and sandhills was collected by USGS using a four KM aerial survey.

Purpose:

REQUIRED: A summary of the intentions with which the data set was developed.

Status:

Progress: REQUIRED: The state of the data set.

Maintenance_and_Update_Frequency:

REQUIRED: The frequency with which changes and additions are made to the data set after the initial data set is completed.
