To redesignate the National Historic Trails Interpretive Center in Casper, Wyoming, as the "Barbara L. Cubin National Historic Trails Interpretive Center".

This section officially renames the existing National Historic Trails Interpretive Center in Casper, Wyoming, to the "Barbara L. Cubin National Historic Trails Interpretive Center." This change honors Barbara L. Cubin, who served as a U.S. Representative for Wyoming. The center provides educational exhibits and programs about the historic trails of the American West, and its mission is expected to continue under the new name.

This section clarifies that any existing law, map, regulation, document, paper, or other record of the United States that refers to the "National Historic Trails Interpretive Center" will automatically be deemed a reference to the "Barbara L. Cubin National Historic Trails Interpretive Center." This ensures consistency across all official federal records and avoids confusion following the name change.

This section makes a specific amendment to the original law that established the center, Public Law 105-290 (112 Stat. 2783). It directly modifies the second sentence of Section 2(a) of that public law by replacing the old name, "the National Historic Trails Interpretive Center," with the new name, "the `Barbara L. Cubin National Historic Trails Interpretive Center'." This ensures the foundational statute reflects the current official designation.
