About this crossing
Historical Context
Opened in the 1920s, Whitlash-Aden supported homesteaders and ranchers in a rugged, windswept region. Named for settler John Whitlash, it facilitated cattle and grain trade, tying isolated communities together. During Prohibition, smugglers ran whiskey and livestock across, with a 1928 bootlegger chase across the plains becoming local legend. The crossing remains small-scale, serving farmers and adventurers drawn to the prairie’s stark beauty. Its history reflects the grit of early settlers who braved harsh winters to build a life here.
Crossing Details and Wait Times
Northbound, you’ll stop at Whitlash’s CBP office for an exit stamp, then hit Aden’s Canadian immigration, needing a passport and possibly a $7 CAD eTA (apply online). Southbound, expect a Canadian exit stamp and U.S. entry rules, typically a passport for visa-exempt travelers. Hours are 9:00 AM to 5:00 PM year-round. Waits are under 10 minutes with no delay reported recently, with rare slight summer delays during local events. Check CBP’s Border Wait Times or CBSA’s CanBorder app for updates. It’s a “Permit Port,” so cargo needs pre-approval from Sweetgrass.
