After Jack dies, Ennis visits Lightning Flat, the home of Jack's parents and where Jack's ashes were sent to be buried. It is said to be along the border with Montana. This is where Ennis finds the shirt of his that Jack kept tucked inside his own from Brokeback Mountain.

"He pressed his face into the fabric and breathed in slowly through his mouth. and nose, hoping for the faintest smoke and mountain sage and salty sweet stink of Jack but there was no real scent, only the memory of it, the imagined power of Brokeback Mountain of which nothing was left but what he held in his hands."
