Stang, this pretty much states WDFW's stance. Their elk specialist made the call on this animal. Contact the undersigned if you want to dig deeper with them.
Dear Mr. H20Hunter,
Thank you for contacting the Washington Department of Fish and Wildlife.
We checked with our elk specialist and he determined from the pictures that it would not be legal to harvest that animal. When we looked at the left antler, it appears that the right antler started to grow an eye guard and main beam but was injured and did not continue to produce points. On page 45 of the hunting pamphlet it gives the definition of the Spike Bull Restriction and does not meet the requirements.
If you have other questions please feel free to contact us again.
Sincerely,
Wildlife Program Customer Service
