ATTENTION: Access to the Facility

USGS requires all visitors to present government-issued identification for access to its facilities.  For visitors presenting a state-issued driver’s license or identification card, USGS may only accept such documents if they are issued by states that are REAL ID compliant or an Enhanced Driver’s License.

As of April 21, 2014, the following jurisdictions do NOT meet the REAL ID standards: American Samoa, Arizona, Louisiana, Maine, Minnesota*, New York*, Oklahoma, and Washington State*.   Visitors to our facility with identification from these jurisdictions must present alternate forms of identification to facilitate access – such as a passport or Federal employee, military, or veteran identification. As this list is subject to change, please check for the most up-to-date information at

* Enhanced Driver’s Licenses are accepted from these states.
