I had a really great response. Then my internet died.
Anyway. GRADUATE. The sooner the better. If you're serious about wanting to be in the industry, time is your enemy. Having a degree is great. They don't give a fuck what it's in, just that you have one. What matters is experience in the industry which I'm guessing you are lacking. Therefor, graduate in fall. Apply for every single office job at a ski resort that you see. But only do it if really is entry level and you are certain you could do the position. It's going to be significantly easier starting at a ski resort.
If you can't find an office job, next best spot to start is hospitality. Apply for front desk supervisor jobs at the major ski resorts. You will absolutely meet industry professionals this way. Once you land this job, send a friendly email to the marketing or events department saying you would love to volunteer for the major events to gain some experience. Keep an eye out, listen and find out who the sales reps are. Talk to them. See if you can help out at any conventions. You're 4 years behind on experience in regards to people who opted to go to college and be involved in the ski industry. Missing another winter will only put you even further behind. Right now there are a lot of old dudes in the industry that are beginning to retire. All of a sudden 20 somethings are taking on jobs that were never available before. Those jobs are going to get filled in the next few years and wont open up again until the next wave of retirees. The meh jobs in the industry cycle out pretty bad, the good jobs... once they are filled, stay filled.
Reason I say all this... I too was anthropology. I live in Mammoth. Made a job for myself in the industry. And I used to work for Malakye.com.... Learned a lot about HR in this industry and what they look for as well as what the current job market.
