Here I've spotted a baleen whale skull to show Kirk - I first spotted this specimen in 2002, and it's still there. It's in a 400 lb block, so it is likely not going to go anywhere for a while unless some heavy machinery is involved. Photo courtesy Ray Troll.
One of the most notable series of fossil localities are exposures of various strata in the Newport Embayment (a geological basin), including the Alsea Formation, Yaquina Formation, Nye Mudstone, and Astoria Formation. The eccentric, extraordinarily gifted, and tragic figure Douglas R. Emlong amassed an incredible collection of marine mammal fossils from this area and elsewhere in the Pacific Northwest during the 1960's and 1970's, prior to his premature death in 1980. One of the purposes of our trip is to visit several of Emlong's famed fossil localities as a pilgrimage of sorts, and pay homage to the great collector.

Previously, in October, I met up with Ray and Kirk when they were in California for a week. We took a day trip down to Santa Cruz where I showed them some fossil localities, and all in all had a rather nice day – although I didn't find a damn thing (thanks to there being little erosion over the prior 20 months). As it turns out, Ray and Kirk have increasingly been picking my brain for details on fossil marine mammals from the eastern North Pacific, and I am pleased and excited to help them with their project; most popular books on paleontology deal with dinosaurs, and very few have ever really touched the subject of marine mammals (Neptune's Ark by David Rains Wallace is an exception). Needless to say, I am very excited for their project to take off.
I found out that if the first fossil locality you go to is kind of ugly and has few fossils (but used to have a lot...), Ray Troll will make you pose with the crappiest fossil you find and a bunch of garbage he finds laying about. Included is a toothbrush, a cardboard mayan calendar, a random photo album (yes, we looked through it) and some other odds and ends; I'm pointing to a rather unassuming scrap of sea cow (Dusisiren jordani) bone. True story.

"It's in a 400 lb block, so it is likely not going to go anywhere for a while unless some heavy machinery is involved."- My cousin's horse is part Percheron, so maybe i can borrow him, lol! Seriously though, i'd take a whack at that thing.
But best of luck on your trip. I can't imagine how much of a treat that must be. And if they are interested in the fossils of the coast, remember to send them my way. I might even be able to take them out to a spot or two and look for stuff.
I know that skull. I'd like some advice on working on similar rocks. I found a vert in a mere 60 lb chunk. It might as well be in cement it's so hard to work.
Yeah, those are a serious pain in the ass. A 60 pound concretion can take up to a month or more of preparation (~3-4 hours a day), in my experience. Generally, it requires a combination of hand tools or a small handheld jackhammer, a pneumatic airscribe, a microblaster, and acid bathing.
Hey good luck in Oregon. If you guys get over to Devil's Punch bowl I recall seeing alot of large whale material in creeks just south of there and interesting pinniped remains south of Beverly. Im sure you guys have some super secret spots that have all the good stuff. I'm hoping to make it out to the Oregon coast sometime this week. I cant wait to see your photos.
