6:43 PM | Geo 730: October 20, Day 658: Looking Back
This is the view from Devils Punchbowl, looking back north to the site of yesterday's photo, Otter Crest. That headland and the next one beyond are composed of Columbia River Basalt. The yellow to gray tilted beds in the middle promontory are Astoria Formation, which was deposited but not yet lithified when the basalt arrived. Those beds, in turn, were beveled off to create a flat marine terrace, upon which the much lighter, flat-lying sands were deposited. The the whole kit and kaboodle was […]

2:56 AM | Detroit Notes: Some Positive Stuff
Despite the grimness of the much of Detroit there are remnants of greatness and, in places, signs of revitalization. Not enough to overcome the large population decline in many of the neighborhoods, but clear indications that the city may have hope of entering a period of split personality with a revitalized core surrounded by depopulated neighborhoods extending to the suburbs. Most of Michigan Avenue, the main arterial from downtown to the west, is lined with abandoned and […]

12:34 AM | Hiking Into Grand Gulch Utah - Cedar Mesa Sandstone and Ruins
Many of you will remember a hike I completed last October in southern Utah (link here). This year, a similar group of friends went into Grand Gulch, a marvelous little canyon located on Cedar Mesa. You can access the BLM web site for Grand Gulch here.I am including many photos from this six-day hike but little details on specific locations.

It's about the size of a diamond and comes from the inner ear of a fish. This tiny construction holds a treasure trove of information, a calcium carbonate microchip made of bone and accessed by a laser. Let's take a look at the science of otoliths.

Then again there are probably tons of illegal …

10:05 PM | Geo 730: October 19, Day 657: Otter Crest Outlook
The view from Otter Crest has become my favorite along the central coast. It's a spot I visited once, maybe twice early in my undergrad years, then forgot how to get to it. It's off of 101, and access is easy to miss if you're not looking for it. So on my first recent visit, last year, I was pretty well blown away by the view. On our July trip this year, we arrived near high tide; during my previous two visits last year, the tide was low. You can see the difference it makes by comparing the […]
