Found an egg mass, need help!!!

[Wisewilhelm]

Hello, this is my first post on this site. This morning, January 15th, my husband found an egg mass attached to the front of his flat bed trailer. I have never seen an egg mass out of water. We do have a creek running on our property but it's about 150 feet from where we found the eggs. We live in Oregon and have an abundance of Pacific tree frogs. Does anyone here know what kind of eggs these are and what should I do with the eggs? I can't leave them on the trailer. My husband uses the trailer for work daily and I worry that leaving them would kill them.
