Sadly their website isn't much help:
"Brewed to have a very powerful hop aroma, this IPA is a very well balanced beer. It has plenty of hop flavor to go around. This beer received the silver medal at the 2003 & 2008 North American Brewers Festival."
A bit more info:
"This medal winning India Pale Ale is brewed in the true Northwest fashion. It has an intense hop flavor and aroma with a dry bitter finish. It definitely has enough hops to "send you over the edge."
IBU: 100 | 13║ Lovibond | 77% AA | 15║ Plato"
Some speculation on the hops: http://snakeriverbrewers.org/index.php?topic=2441.0
Try getting in contact with the brewer to find out what hops they use.
