    Rapid Erosion Supports Creation Model by Frank Sherwin, M.A. | Jan. 25, 2016 Recently in Dorset, England, bad weather washed a massive section of a cliff into the sea revealing scores of ammonite fossils.1,2 Creation scientists are interested in this cliff fall because substantial erosion was accomplished in literally seconds. It didn't take hundreds of thousands to millions of years of slow and gradual erosion. The cliff fall at Dorset isn't the only recent example of rapid and significant erosion. Uniformitarian geologists claim the famous White Cliffs of Dover, composed of calcium carbonate, were formed in the Cretaceous Period between...
  • Second world war dead washed up by Pacific Ocean's rise - caused by global warming

    Skeletons of second world war soldiers are being washed from their graves by the rising Pacific Ocean as global warming leads to inundation of islands that saw some of the fiercest fighting of the conflict. On the day Europe commemorated the 70th anniversary of the storming of Normandy beaches in the D-Day landings, a minister from the Marshall Islands, a remote archipelago between Hawaii and the Philippines, told how the remains of 26, probably Japanese soldiers, had been recovered so far on the isle of Santo. "There are coffins and dead people being washed away from graves; it's that serious,"...

    Cavitation by John D. Morris, Ph.D. "One glance at Grand Canyon evokes wonder at the extensive erosion that occurred—but the canyon is only the final whisper of a grand-scale event. The massive erosion episode leveled off and gouged out the Colorado Plateau, covering much of Arizona, Utah, New Mexico, and Colorado. The present-day Colorado River hardly seems capable. Something of a much larger scale accomplished this!...." more...
  • The American Left and the Erosion of Public Discourse

    American Thinker ^ | 3/8/12 | Steve McCann
    Much has been made of the precipitous decline in the level of discourse in the United States. Many attribute this to the coarsening of the language and the ever-widening gulf between the various factions in the political spectrum. However, these factors are a symptom of a current underlying and foundational dilemma: the inability of not only the general public, but nearly all of the so-called societal leaders and opinion-makers to generate an original thought, as well as a stubborn refusal to use reason and logic when confronted with irrefutable facts and arguments. These traits can be explained, insofar as the...

    If an arch falls in the desert... Sorry about last week, I literally lost track of time. So here are several images from another of those amazing state parks in America, this one called the Valley of Fire State Park in Nevada, which is within driving distance of Las Vegas (and you can apparently drive through part of it). The reason for this particular posting is that one of the many arches in the park fell down very recently. Erosion happens. When you see the arch that fell down, you can understand why; this one was pretty precarious. Article: Valley...

WELEETKA — Authorities working to narrow their leads in the June 8 shooting deaths of two girls used old-fashioned legwork to come up with a list of area gun owners with .40-caliber pistols, one of two weapons used in the slayings. Oklahoma State Bureau of Investigation agents knew the caliber of the guns used in the killings, so they merely checked with area gun dealers and pawnshops to determine who had bought or recently pawned .40-caliber Glocks.

It is called "Georgia's Little Grand Canyon", and it formed due to drastic erosion caused by non-soil-conserving agricultural practices.

    For today's Halloween GPoW, I challenged myself. I have frequently posted pictures of volcanoes, waterfalls, caves, arches and bridges, canyons, and mountains; I've occasionally veered off that path with landslides, remote-sensing views, and a couple of crystals and minerals. So my challenge was to come up with something DIFFERENT; unusual, photo-worthy, and significant geologically. And also something a bit relevant to Halloween. See if you think I succeeded. All of these are in the United States.

    Far too few among the Christian community are willing to remain steadfast in their beliefs, in the face of the enormous pressures of liberal social change. Fortunately, Bruce N. Shortt exemplifies the meaning of such worthy resolve. Last year Shortt, along with T.C. Pinckney, made waves at the 2004 Southern Baptist Convention (SBC) by stating the obvious. America’s educational system has, over the past several decades, completely degenerated from any pretense of promoting academics. Instead, it is primarily focused on a program of indoctrinating students towards countercultural social transformation. Relentlessly working to eradicate any references to God or traditional morality,...

    Despite extending the unprecedented 30-hour talkathon on the Senate floor by more than nine hours, Republicans failed to force a vote on President Bush's three judicial nominees deemed too conservative for the American mainstream by Democrats. Republicans launched the round-the-clock debate Wednesday night to counter Democratic filibusters on the nominations of Texas judge Priscilla Owen and California judges Carolyn Kuhl and Janice Rogers Brown. At the outset, Democrats warned the Republican tactic wouldn't work.
