Chinook Pass, an 11-time stakes winner and the only Washington-bred to win an Eclipse Award, was euthanized May 31 at owner Jill Hallin's farm in Maple Valley, Wash.

Chinook Pass, who was 31 at the time of his death, was believed to be the oldest living Eclipse Award winner.

According to Hallin, Chinook Pass had a high pulse rate and was in distress from heart malfunction.

"He brought so much joy to my life," said Hallin, who had owned Chinook Pass since 1988. "It's a very sad day, but he had a long and wonderful life." Foaled and raised at Dewaine Moore's Rainier Stables in Enumclaw, Wash., Chinook Pass won or placed in 21 of 25 starts, including 15 stakes races, and earned $480,073 for owner Ed Purvis and trainers Bud Klokstad and Laurie Anderson
