Investigative Judgment; AT Reporting; etc.
I thank you, John McLarty, for the brilliant article on the Investigative Judgment, which portrays a beautiful picture of a loving God who reaches out to people of all times, places and situations with the best He has to offer! After hearing, reading and preaching on the judgment for over 50 years, I am happy to see this article which brings beauty and clarity to this subject which so many of us have struggled to understand within the framework of the Gospel. Might this clarification fall within the category of things we "need to learn" and also involve some things we "need to unlearn"? Dick Serns
Loomis, California
I am overwhelmed with appreciation at the issue of Adventist Today that arrived today in my home. I have already read it from cover to cover. My mind is etched with a sense of positive purpose that this publication shares. I read the letters in "First Class" and see that others share my feeling. Not everyone! I am refreshed over and over when I see truth shared in an open environment. I spent too long in denominational employment where that was not the case [26 years as a pastor]. I am not vindictive at heart. I love my church. I have always wished for a denominational setting where I could share from an open heart, without fear of losing my job or reputation. That is what I am seeing in Adventist Today. Don’t let that ever slip away!

Agate Fossil Beds
National Monument
Located on the Niobrara River in northwestern Nebraska, Agate Fossil Beds National Monument and its surrounding prairie are preserved in a 3,000 acre national monument. Once part of "Captain" James H. Cook's Agate Springs Ranch, the nearby beds are an important source for 19.2 million year-old Miocene epoch mammal fossils. Cook's ranch also became a gathering place for Chief Red Cloud and other Oglala Lakota (Sioux) Indian people. The monument's Cook Collection of American Indian artifacts reflects years of gifts brought by the Indians during visits to the ranch from the 1880's through the early 1900's.

Volcanic ash magnified 525 times. All Ashfall skeletons are buried in a bed of pure volcanic ash. Volcanic ash consists of tiny shards of glass from broken glass bubbles. These glass bubbles form and then break apart during powerful volcanic eruptions.
The ash particles are small enough to have been breathed deeply into the lungs of animals when volcanic ash blanketed northern Nebraska twelve million (12,000,000) years ago.
At the Ashfall fossil site in northeast Nebraska, the ground beneath the soil looks something like this in cross-sectional view.
Sedimentary rock layers (strata) contain fossils that reveal clues to environmental conditions and the animal life of specific times in the past. The particles of sediment that make up the rock reveal clues about the environmental setting and how the rock was deposited. An aerial view of a portion of the Ashfall site. MORE

Ashfall Today Unfortunately, a time machine does not exist that would enable you to take a journey back 10 million years ago. But, the Ashfall Fossil Beds State Historical Park may be the next best thing. When you visit the Ashfall Fossil Beds State Historical Park you may get to talk directly to paleontologists like Michael Voorhies who's kneeling here. The Rhino Barn covers only one percent of the fossil beds, but it shelters the most important and interesting 10-million-year-old skeletons exposed so far. Source - Game and Parks Commission. See how the Park was built in this video . You'll need the QuickTime Player The park is located between Royal and Orchard in Antelope County in northeast Nebraska. Inside, the animals are still locked in their death-poses and are amazingly well preserved skeletons. Michael Voorhies and his colleagues made the decision to excavate the site and leave the animals in their positions, rather than removing the skeletons to the museum. Visitors can visit this time capsule and view what Nebraska wildlife was like long before modern human beings ventured onto the Great Plains. Ashfall is unique in that animal skeletons are still joined together in the proper order, not bones scattered over a wide terrain over a long period of time. The silent, ominous cloud of ash that rolled across Nebraska and eventually buried the animals has preserved them and offers scientists and visitors a unique glimpse into their lives.

As far as fossil remains go, almost always, only scraps of bone or shell or a few carbonized leaves are all that remain of past organisms. Too often the soft parts decompose, and even the hard parts degrade. In some exceptional instances however, usually anaerobic environments, or a sudden mudslide or volcanic eruption, organisms are buried before their bodies can be broken down by bacteria, or consumed by scavengers. Eventually their bodies are carbonized or mineralized, and so even soft-bodied creatures become fossilized. Such environments provide a unique, rare and precious window to the past. These extraordinary fossil deposits, where organisms are so well preserved that even their soft parts remain as carbon films, are referred to as Lagerstätten , a German word meaning "deposit places". These are geological fossil deposits that are rich with varied, well-preserved fossils, representing a wide variety of life from a particular era. These spectacular fossil deposits represent a window into the past, a kind of "snapshot" of the type of organisms (hard and sometimes soft-bodied) that lived at that particular time and place.

By Ann Hattes Grab a trowel and brush, leave TV's Barney and Steven Spielberg's Jurassic Park creatures behind, and start digging for real dinosaurs. In Colorado, Montana, Utah and Wyoming, paleontologists have uncovered hundreds of species, from flesh-eaters to egg-stealers. "It's hot, dirty, fun, educational and great family time," said Joseph Cornwell, president and executive director of Montana's PaleoWorld Research Foundation. "Nothing compares to the excitement as participants uncover an animal some 65 million years old." The following sites offer opportunities for the public to unearth fossils and/or see dinosaur bones upclose. Due to summer heat, it's best to visit the sites in spring or fall; some aren't open during the winter. Many of these places are remote; be sure to bring water. COLORADO

Localities of the Eocene:
The Florissant Formation
This pleasant green valley, set in the eastern Rocky Mountains of Colorado not far from Pikes Peak, is the site of an important fossil deposit that provides a look at life in the late Eocene . Thirty-six million years ago, volcanic mudflows blocked a stream flowing through this valley, producing a lake about twelve miles long. Vegetation flourished on the shores of this lake, and the valley came to teem with life, until about two million years later. At that time, about thirty-four million years ago, a new series of periodic volcanic eruptions began about fifteen miles away, in what is now South Park, Colorado. These eruptions spewed out fine-grained volcanic ash (much like the ash spewed out by Mount St. Helens in 1980), which choked and eventually filled in the ancient lake and valley. The fine ash rapidly buried countless plants, insects, snails, and other animals, preserving them beautifully in the process. Today, these ancient ashfalls are named the Florissant Formation, after the Florissant Valley and the nearby town of Florissant. Tens of thousands of fossils from the Florissant Formation have been collected and studied since the late 19th century; they can be found today in museums around the world. Most of the Florissant beds are protected by the Federal Government, making up Florissant Fossil Beds National Monument. Some private quarries do exist in the area where the general public can collect fossils.

    Fossil Skeletons and Mother Lodes
    For those who have collected old bones and teeth from Florida, you can attest to the fact that although fossil mammals are indeed plentiful, they are usually found disarticulated; the skeletons are almost never found in tact. Localities throughout the world that do preserve complete skeletons are indeed rare and these have been called Lagerstätten , a German term roughly meaning "mother lode." Steve Gould once noted that ".Lagerstätten are rare, but their contributions to our knowledge of life's history is disproportionate to their frequency." Why is this so? For invertebrates, soft-bodied organisms may be preserved thus giving insight into various fossil groups not normally fossilized (see Book Review below). For vertebrates the same can be true. At the fabulous Eocene Messel in Germany, carbonized impressions of stomach contents of palaeotheres (close relatives of horses, see chart on page 6) indicate that they were eating grapes, and that bats were eating butterflies. For other Lagerstätten containing vertebrates, the Scientific value is in the completeness of the skeleton. These entire specimens allow paleontologists to decipher the anatomy and biology of these extinct organisms. Artist Marc Marcuson's reconstruction of Pliohippus

View looking west towards Twin Diapirs (Carboniferous-Permian evaporite diapirs) in the forground, and Split Mountain (to the right) on Kanguk Peninsula, western Axel Heiberg Island, Canadian Arctic. The youngest units visible are the black basalt flows of the Strand Fiord Formation, capping cliffs over 800 metres tall on Split Mountain, about 6km away. These are underlain (in order) by thin black shales of the Bastion Ridge Formation (marine), the Hassel Formation (sandstone, nearshore marine) and Christopher Formation (shale, shelf marine), all Cretaceous in age, and the subjects of the study. In the foreground, around the orange-yellow diapirs, some of the sandstone of the Isachsen Formation is visible. The orange-yellow colour of the diapirs is caused by oxidation of sulphide minerals associated with the diapirs.
