- Each parcel symbol shown on the map is given a classification related to construction aggregate lease activity or sand and gravel resource potential. The five classifications and general descriptions are:
Active Lease - Parcel is currently leased.
Historic Lease - The parcel has been leased previously and may be available for a new lease. 
Candidate - Aggregate resources are inferred based on digital data and DNR field observations. Additional field investigation is needed.
Prospective - Aggregate resources are inferred based on digital data only. Additional field investigation is needed. - Map Tools Details

Exploration of Candidate & Prospective Parcels
A DNR permit is required for on-site field exploration. Access conditions will vary by parcel and leases are not guaranteed. The DNR has a separate aggregate mapping program providing county-wide aggregate resource maps to assist with land-use zoning planning. While observations from the mapping program supplement the information provided on this page, certain methodologies or conclusions may vary. For more information please visit:

The DNR does not operate a retail business to sell stone products or construction aggregates. Lessees identified on the map may be contacted directly, please send an email inquiry to the aggregate leasing program if you would like assistance reaching a lessee.- Use and Data Disclaimers
