Are they shriveled looking? If so they are likely done for.
You can take one and scrape the bark to see if it is still green under the brown outer layer. You could also trim a little of the end of one to see if the inside still has any moisture. If you would have put them in plastic and put them in a fridge they would be fine.
It's tough to say if they are still good or not, one thing is for sure, they will probably mold pretty quickly if they are dead. You'll know within a couple weeks if they are viable, and there is not much you can do about it now. Well, other than try get some more cutting from that tree before it gets removed.

They weren't shriveled at all. They actually look exactly the same, with the green ring underneath the bark. I guess I'll keep an eye out for mold and see if I can plan another trip out there. Thanks for your help.

Plant them in a pot of soil and see what happens!
