Lassen Peak Erupts in Northern California
Lassen Peak, a volcano located in northern California, erupted explosively, sending ash and steam into the atmosphere. This significant geological event marked the return of volcanic activity in the region after thousands of years of dormancy. The eruption created a series of eruptions over several years, attracting scientists and spectators to study and witness volcanic behavior. The forceful activity of Lassen Peak is particularly noteworthy as it became the only volcano besides Mount St. Helens to erupt in the contiguous United States during the 20th century, highlighting its geological importance.

The eruption of Novarupta in Alaska began on June 6, 1912, marking the largest volcanic eruption of the 20th century. Located on the Alaska Peninsula, this explosive event released around 30 megatons of energy, producing a vast ash cloud that spread thousands of miles across North America. The eruption lasted for several days, culminating in the formation of the Katmai caldera. The eruption was so powerful that it altered local landscapes and had significant effects on climate patterns, demonstrating the scale and impact of natural disasters. Volcanologists studying this eruption noted its importance in understanding volcanic activity.

The Piedra Movediza, a famous rock in Tandil, Argentina, known for its precarious balance and attraction to visitors, fell from its position and shattered on the ground. This natural curiosity had become a symbol of the region, drawing crowds who marveled at its unique ability to appear as if it were perpetually on the verge of toppling. The event occurred unexpectedly, leaving locals and tourists surprised and saddened by the loss of this geological marvel.

German geophysicist Alfred Wegener first presented his groundbreaking theory of continental drift at a meeting of the German Geological Society in Frankfurt. Wegener proposed that continents are not fixed in place but move across the Earth's surface over geological timescales. His ideas were revolutionary, challenging the existing geologic opinions that had dominated for decades and laying the groundwork for later developments in plate tectonics. He argued that the continents once formed a single landmass called Pangaea, which eventually split apart and drifted to their current positions.

In 1909, paleontologist Charles Doolittle Walcott discovered an extraordinary fossil bed in the Burgess Shale, located in the Canadian Rockies near Field, British Columbia. The fossils, stunningly well-preserved, include a variety of Cambrian organisms, offering an unprecedented glimpse into early life on Earth. Walcott's finding, which came after extensive exploration, highlighted the diversity of marine life during the Cambrian period and fundamentally changed our understanding of evolutionary biology.
