The Stevens Pass website lists all their daily lift ticket starting times and costs under their root Tickets & Prices - Lift Tickets page.  They use a card system which has an embedded RFID (radio frequency ID) chip that is scanned as you funnel through the lift line gate just before getting on a lift.  Essentially you purchase the card (known as "daily access media" or an "RFID card") which can be reused by reloading it on-line on their website before you head off to the mountain.

Stevens Pass also has Seasons Pass sales that when purchased during the off-season for the next year will save you quite a bit of money.  They also have a discounted lift ticket program known as the Advantage Card program.  Check them all out on their website!
