Sorry to hear about your unsuccessful trip. I have a trip to the Yukon scheduled for Aug 2023 and I was wondering if you would mind sharing the concession number or even the general geographic area of the Yukon you were hunting. Of course, if you wanted to share the outfitter name that would be fine too.
1. How many square miles in the concession?
2. How much of the concession is mountain range e.g. Ogilvie Mountains? The Yukon concessions...some are "more better" for moose/grizzly/caribou and some have more (or less) habitat for Dall/Fannin sheep.
3. Ask the outfitter "How long have you/your family had this particular concession?"
4. The Yukon has seen some tough winters and then some "Spring Thaw" with ice storms where the previously-cleared sides of mountains turn to ice, and the sheep starve. Entire age class gone.
5. There are certain areas of the Yukon that have lost up to 50% of the sheep population. For example, the Spring of 2013 was horrible north/northwest/northeast of Dawson City. Sheep starved/froze to death in March/April. Areas "that had up to 3000 sheep are still at 1800 sheep and haven't recovered".
6. Try to get some of the data from the "Thinhorn Sheep Conferences", or whatever the "Thinhorn Summit" meetings are called in Canada. Populations are down in the Yukon since 2013 due to at least three bad winter-kills and haven't recovered. Some areas and pockets did okay but the overall numbers are down.
7. Ask your CA outfitter how many sheep hunters they are taking per year, and is this the same number as prior to 2013? Success rate and average age of rams taken?
8. I am a US citizen, and have hunted sheep in OR in 2009, in the Yukon in 2012, 2013, BC in 2014, the Yukon in 2015, 2016, Idaho 2018 and Mexico 2019 and back to the Yukon one month ago. You have to pay more in CA as compared to most sheep hunts in OR/ID or AK, train the same like your life depended on it, and keep an optimistic attitude. I was lucky enough to be the only person to draw the OR and the ID sides of Hell's Canyon through the non-resident random draw. Book rams both times and dang near died in OR due to persistent rain/sleet in late October, and lots of hiking in ID as we came in from the backside and didn't go near a jet boat.
My main suggestion, assuming you are training/shooting/weaning down your gear list to a minimum, is to find out the # of hunters/year over the past 10 years, the ages of rams taken, and get references of successful and unsuccessful sheep hunters. Just my two cents, and I'm heading back to the Yukon next year. I will not divulge the outfitter, but the adjoining outfitter concession has not decreased their # of hunters while the outfitter I'm hunting with has decreased his # of hunters by 1/3 so as to maintain an older age class of animals.
I don't spend a lot of time on social media so may not be back to respond as I'm going to out of the country a couple of weeks hiking the Camino de Santiago in Spain with my wife and planning to stay away from the internet for awhile.
Bryan Martin, about 6-7 years ago, posted some interesting comments on the "Stone's/Dall's/Fannin's" sheep hunting data/opportunities in CA. You may be able to find a Rokslide member who copied/pasted his comments.
Best and good luck,
