Furthest inland you can see the Ocean (in Oregon)

[julius]

does anyone know, on a clear day, whats the furthest inland you can see the Ocean in the state of Oregon?

I know there's Marys peak near Corvallis where you can see it. At least, that's the story I've heard.

I don't know the answer but I was told it was either Mary's Peak or another coast range one.

Sounds like a a viewshed problem in ArcGIS. You just need a good, accurate DEM and about 10K (a year) for a software license and you should be in business.

At the risk of sounding like HCP...

Huh?

Anywhere, on webcams. I can see it right now. Appears to be night there too.

This is much simpler. Back in the old days we'd use a giant mirror and helium balloons.

Why do you need to know? Got a date? Just got hired as a submarine spotter?

on the central coast Mary's peak is the last thing to disappear from a boat going west. seen it many times. very likely the correct answer as highest points in the coast range north and south of there are closer to the ocean.

Science-y stuffies.

Speaking of submarine spotting, here's a new article you might like, Brian, timed for Pearl Harbor Day.

The Japanese had 3 400-foot submarines carrying fuel to islands. Each had been designed to carry 3 bomber aircraft. After the war, one was brought to Hawaii to inspect the new technology, then was sunk 2300 feet. Now, submersibles are looking at it.

Not the answer I expected from Maris.

You can't see it from Bend, FAMS?

Maybe from Paulina Peak. Just a few feet under 8,000. You can see Idaho and California and Nevada and Washington from there.

Nope, not from Bachelor either. Here's a link to a calculator that computes distance you can see to the horizon based on altitude. http://www.ringbell.co.uk/info/hdist.htm

Paulina Peak at 8,000 feet would only give you a distance to the horizon of about 110 miles and it's about 230 miles to the coast from there. Mt. Hood is about 11,200 feet in elevation, would give a horizon distance of 130 miles and the coast would be about 160 miles away. Mary's Peak is 4,098 feet in elevation, which would give a horizon distance of about 78 miles and the coast is only about 25 miles away. The location would have to be in the Coast Range. The five highest points in the Coast Range are:

Marys Peak, 4,101 feet
Rogers Peak, 3,706 feet
Grass Mountain, 3,615 feet
Laurel Mountain, 3,592 feet
Bone Mountain, 3,547 feet

The farthest inland of those points is Bone Mountain, which is about 31 miles from the coast. I'd go with that as the answer to this question.
