The deepest point on land ever discovered—over 2 miles below sea level.
The lowest spot on land isn’t a desert basin or a salty lake—it’s hidden under ice.
Beneath East Antarctica’s Denman Glacier, the crust surface plunges roughly 2 miles (about 11,500 feet, or 3,500 m) below sea level.
That's more than eight times deeper than the Dead Sea (the lowest surface point on land) and about a third as deep as the Mariana Trench (the deepest point in the ocean).
This extreme depth isn’t carved by rivers or open water, it’s shaped by how ice and rock interact over long periods.
Thick ice presses down onto the crust, flowing ice tugs and grinds at the surface of the crust, and the shape of the buried landscape feeds back into how the glacier moves.
Where the surface of the crust plunges below sea level and slopes inland, ice thins and retreats more easily.
Ridges serve as "brakes" that slow and channel the flow of the ice toward the ocean.
The Denman “abyss” only appeared clearly when a new mapping effort—BedMachine—"cleaned up" the old terrain maps.
When current ice‑flow models didn’t align with the older terrain maps, it became clear that the old bedrock maps were wrong.
By combining radar soundings, seismic data, snow accumulation studies, and ice‑flow information from 19 research groups, the team built a much sharper view of Antarctica’s buried topography.
The results revealed the Denman trench in striking detail—the deepest point on land ever discovered.

(May 9, 2026) Of all places, Louisiana has a lake that shows signs of be an "airburst" comet explosion similar to the Siberian Tunguska event of 1908,

A shallow Louisiana lake hides the scars of a powerful ancient cosmic airburst impact.
Beneath the tranquil surface of a Louisiana lake lies evidence of a cosmic catastrophe that occurred near the dawn of human history.
Here, the landscape appears to have been reshaped by an explosion so intense it melted the ground and blanketed the area with microscopic glassy spherules.
This is the Perkins site, near Perkins, Louisiana—now recognized as North America's first identified airburst crater, dated to the onset of the Younger Dryas period, a sudden and anomalous cooling in Earth's climate.
The Younger Dryas Impact hypothesis suggests a fragmented comet struck Earth's atmosphere 12,800 years ago, triggering abrupt, widespread cooling that contributed to the extinction of numerous animal species.
Scientists exploring this unassuming, shallow depression—stretching nearly 1,000 feet (300 meters) across—have uncovered billions of fused spherules and large fragments of high-temperature meltglass, clear markers of an extreme cosmic event.
What distinguishes Perkins is not only the vast quantity of impact materials, but also the presence of abundant shocked quartz grains—a mineral signature almost exclusively linked to confirmed impact sites.
Chemical and structural analyses reveal that the spherules and meltglass here closely resemble those from renowned impact craters worldwide.
The exceptionally high concentrations of meltglass and spherules at Perkins rank among the greatest found at any known impact or airburst site, highlighting the scientific significance of this discovery for geology and our understanding of cosmic hazards.

(April 21, 2026) It took off, but it did not reach its goal. And now it's going to have an early re-entry, v***ring in the atmosphere.
