Excellent presentation! LiDAR really is amazing.

LIDAR is a tool as may be Thermal Imagery, Whoops... another cat is outside their bag..

I live 3 miles south of mima mounds in Gate. There are old sketches that show our prarie was covered with mounds also but were leveled for farming shortly after it was settled. They look like whats left after water has receded from a flat area like the little ripples of sand that are created on beach in certain areas when the tide goes out.

Mima mounds. If you put a big black rock on a sheet of ice, eventually it heats up and melts down. That little dent makes a place for wind blown.sand and dirt to gather. Which of course heats up, and melts into the ice. Eventually you'll have a bunch of growing bowls full of dirt on the top of the ice. And when the ice retreats, those bowls will be on the ground, inverted. I would think this kind of thing would be more likely on the leading edge of a glacier. Because you need to be close to some sand and other crap that would blow in. My cute little theory could be confirmed by excavating one of these and seeing if there's a rock at the bottom, in the middle, that would have been the seed.

A lot of them are found on flood scoured basalt surfaces that didn't have glaciers, out in the scablands way far away from the ice lobes. They've been excavated many times and I've never heard of any central nucleating rocks being found in them.

Nice presentation. Lidar is great. The most revealing tool for seeing and analyzing landscapes yet devised. Continued improvements in coverage and detail level will enhance its already huge value.

I live near brinnon and the underwater shelf is massive from 20ft to way over 800 ft deep, trident subs can hide underwater and test fire torpedos, the stuff I've seen is amazing

Awesome images. Such a cool presentation. Can you make a book with explanations of what each feature is, how each feature formed, when each one formed and how it formed? Would be so cool to see the story of each map with more details.

Nice presentation. Is there something like this for Oregon and Lake Alison?

@jcee2259 4 ай бұрын

Oregon can talk the talk but Oregon is not walking their walk with me. I prefer visiting explorers of the British Columbia Speleological Federation..

I have admired your work since Nick presented it to the world at large. The Mt Rainier glacial extent image at 23:30 is intriguing. There is a large percentage increase in glacial ice area from '08 to '24. Do we have an ice thickness map that can be contrasted against this picture? Is Mt Rainier the canary in the coal mine for MWP 1C?

As awesome as this work and presentation, can we please get the basics in the description: speaker, affiliation, date, place, time, venue. contact information.

I thought there’s midden 14500 in puget sound So when was it “covered” in ice. And parts of Vancouver island (brooks peninsula) remained ice free? So my ignorance is still an issue. ?

The Mima mounds are the exact same form as star dunes found in the desert, but they are actually wave ripples produced by interference. There you go, a logical explanation of their creation.

This is what I do using Grade-5 cartography amid Pacific Northwest Karst, Starting from the nearest brass USGS fixture. So my finished work allows us to see where my cave transit is exactly under all known terrain. Often I follow surface water down into the Water Table. Where holes are drilled to pump out liquid for public or private usage. I also catalog Troglodytes. The longest map in the USA shows more than 500 miles of found extent. To go through all that you need organization for provisions and services. Underground base camps usually occur 12 to 18 man-hours apart. This assumes reader did not get lost amid uncharted cave. Hello ?

Excellent and amazing work. I use ypur site and images for work

These drumlins exist all over the world, even where there never was a glacier like the Sahara desert. We have much higher resolution lidar images of Norway, Sweden and Finland down to 1 meter and 2 meter resolution. They show the exact same landforms.

Amazing..!! Now could you please go through all your "artistically skewed" images, and overlay a Noth indication arrow. Or keep them northerly oriented, So they look cool AND make sense.

Is there evidence of the Puget Lobe backfilling the Elwha River Valley? I hypothesize glacial tongues with corollary tunnel channels (Lesemann) overflowed low mountain passes in the Vancouver Island and Olympics (out of the Elwha and Hood Canal.)
