A River Runner’s Guide to Grand Canyon Geology IV: Whither the Supergroup?
We left off the last post having seen the complete Supergroup sequence of over two miles of Neoproterozoic and Mesoproterozoic sediments. The river never encounters the Neoproterozoic part, roughly half. These lie above the river on the North Rim side … Continue reading

A River Runner’s Guide to Grand Canyon Geology III: The Supergroup
A typical visitor to the Grand Canyon looks down from the rim through about a mile of sediments to the river. Most of these are Paleozoic sediments extending back about 515 million years. They appear to be level, although in … Continue reading

Entropy and the Grand Canyon
It has been our good fortune to row 280 miles of the Colorado River through the Grand Canyon twice in the last seven months. This is rare for private boaters limited to one trip per calendar year and subject to … Continue reading

Differential Motions of the Continents, Mesozoic and Cenozoic Eras IV: Constraints
We know the position and velocity of stable points on our six cratons. A reasonable question to ask is, “Can we account for this motion?” Above is a map of the ocean floor created in the last 10 million years. … Continue reading

Shiprock
This picture was taken in September 1979. There is a print of it in my office, faded a bit. When I wax geological, the sheer improbability of this mineralogically unusual salient weighs heavily. High in Magnesium, Potassium and Sodium; low … Continue reading

Oil and the Devil
The concept of the devil in the Judeo-Christian/Muslim tradition seems to have its roots in an older Persian and possibly Indo-European notion of opposing forces of good and evil. The Christian conception developed into the elaborate scheme described by Dante which was integrated into … Continue reading

The State of the Onion
Let’s say the way this planet works is an onion. There are many layers and they interact in ways far more complex than onion rings. Yet we have to start somewhere, and peeling back the layers of this onion can … Continue reading

The end of the Hollowscene
The concept of the Holocene epoch is a 19th century notion developed when the preceding “ice age” was thought of as a monolithic block of ice extending back to the end of the Pliocene. In this context it made sense … Continue reading

Aftershocks Implicate Unusual Fault System in American Canyon Quake
California can be thought of as a ice flow where multiple independent blocks with different inherent buoyancies are at times pressed together, pulled apart, and slid past each other. The M 6.1 American Canyon quake did not take place on … Continue reading
The Pacific Triangle, The Pacific doughboy, and the wave
Folks just don’t seem to have their arms around the disarray in the earth sciences these days. Climate science and plate theory are going to have to be rebuilt from the ground up, or more appropriately from the core-mantle boundary. … Continue reading
