The Lake Malawi Sediment Chronometer and the Toba Super Eruption

Mt St Helens, Washington State

The site of one of the largest volcanic eruptions in earth’s history, the effects of the Toba Super Eruption have been of considerable interest to archaeologists and anthropologists because of its potential impacts on past human populations.   New research exploring the Toba Super Eruption (Sumatra) has been published since I explored the implications of the […]

The YDB Event: The Most Recent Global Catastrophe in Human History?

The chebli9ska meteorite atmospheric explosion as caught on dashcam of truck..

Remember the meteor that exploded over Russia earlier this year? A 50 foot diameter object exploded 14 miles above the surface of the earth and created a shock wave that injured 1500 people and damaged more than 7000 buildings. Despite the drama, the lasting effects on the earth were minimal and only small pieces of the meteorite made it to the surface of the earth.

Implications of Artifacts and Bones on Ancient Human Butchery Practices

A recently published study is making news the last couple of days. It regards evidence obtained from remains of preserved bones of human scavenging and/or hunting practices.   The site of the dig is a hillside in southern Kenya where, in less than an acre, more than 3700 fossils and more than 2000 artifacts have been recovered […]

NH Notes: Answers in Genesis and a Mountain of Extraterrestrial Dust

mars-whole-planet

How long would it take for falling dust to accumulate into a mound 2 1/2 miles tall?  Answers in Genesis has commented (Wind, not water, may have built the Martian Mount Sharp) over the weekend on the same research article that I referenced in my post last week (NH Notes: Did Wind and Dust Create a […]

Curiouser and Curiouser: A Mars Curiosity Update

After the Mars Science Laboratory, otherwise known as the Curiosity rover, dropped down the rabbit hole and safely landed on the surface of Mars there was much ado about the first images and hints at a watery past.   Since then the rover has left the public eye but the rover has been no slouch, […]

The Worlds Largest Rock Tumbler and the Age of the Earth

Atacama-wind-erosion-rock

Last year I wrote about the strange rubbing boulders of the Atacama desert.  In that post I relayed the story of these strange large boulders that are found scattered in a high valley in the Atacama desert.  That desert is one of the driest places on earth with the area that these particular boulders lie […]

More Planets Than Stars – Exoplanets and Our Little Blue Ball

exoplanets-earth-like-planets

To say that the Universe is a big place would be a huge understatement.  It is difficult to fathom just how big it is.  When we hear that there are an estimated 10 sextillion to 1 septillion stars in the Universe we have few reference points to compare to those numbers. A number followed by […]

NH Notes: Snapshot of a Chaotic Tumbler – Asteroid Toutatis

Toutatis-image-chinese-probe

A Chinese spacecraft has been only the fourth to fly past an asteroid and capture close-up images.   Here are a series of images of the 4 km long asteroid Toutatis which is considered a NEA (Near Earth Asteroid) though it won’t make another pass near the earth for another 50 years.   This is […]

Weekend Potpourri: Salt Chronometer Update, Ken Ham Blog, and Gen X Creationists

potpory

It has been a while since I’ve been able write. There has been quite a bit of news the last two weeks and I thought I would briefly comment on a few items that are relevant to my most recent posts: The Salt Chronometer Since I published my series on the salty seas (Part I, […]

Lake Suigetsu and the 60,000 Year Varve Chronology

Here is an example of an ash layer from one of the cores of Lake Suigetsu.  This ash layer is more than 1cm thick (the varves are less than 1mm each) and is composed almost almost pure volcanic glass. The purity suggests that it resulted from ash falling from the sky into this very placid lake and quickly sinking to the bottom.  This image is from the Suigetsu web page:

Layers of sediment underlying some lakes can be read like rings in a tree. These layers called varves (alternating layers of sediments and/or organic material) and the precise counting of one that represent annual layers have been used to test and calibrate radiocarbon dating methods.   A few weeks ago there was a report on additional […]
