"These horses need help," said Debbie Logstrom Avalon Mist Equine Rescue manager. "This is no way for them to live."
Logstrom and other locals have banded together to keep the horses alive and as healthy as possible - giving them spare hay from their farms.
"As you can see out there, there's nothing to eat. Absolutely nothing but weeds," said Sherry Fryar who has brought the horses say. "I did spot some horses eating tumbleweeds the other day. I think that's part of the reason the babies are in bad shape."
KIMA wasn't able to see those babies because the property was fenced off. Fryar insists they're farther away and that the only reason some of the horses looked okay is because neighbors are feeding them.
One of them shared video of an emaciated colt and pictures of horse bones on the property. Action News spotted the bones.
The Yakima County Assessor's Office confirms the pasture sits on tribal land.
Yakama Nation Chairman Harry Smiskin acknowledges the horses are neglected. However, he said his investigators have not seen any dead horses.
Smiskin said the land is currently being leased, but that the renter doesn't own the horses. He would not confirm who the animals belong to.
The Nation's Game Warden says the tribe has tried to find him, but all attempts have come up empty.
Fryar hopes the horses can be saved.
"I would like to see the horses taken, adopted out, and babies that can be saved right now go to the vet," she said.
Chairman Smiskin said investigators were headed to the property. Action News will follow up and tell you what they found.
