This is so sad to hear..and so true, the horse world has lost great horses the past few months. I'm sure more information will be released later but I can't find much as of now. NRHA
"We have received notice that Smart Chic Olena has passed away due to natural causes.
The 2004 NRHA Hall of Fame inductee and NRHA Five Million Dollar Sire will be greatly missed by the reining horse industry.
We send our condolences to all of those involved in his show pen and stallion successes.
The 1985 stallion was the 1993 Open Reserve World Championship under Craig Johnson, in addition to garnering Gold and Silver Certificates with the Association.
In AQHA competition, Smart Chic Olena earned World Champion honors in both Senior Reining and Cutting."
