Parkdale Lava Flow

Unveiling the Parkdale Lava Flow, a geological marvel and cultural treasure, this captivating exploration delves into the intricacies of its formation, ecological significance, historical impact, and recreational opportunities.

Emerging millions of years ago, the Parkdale Lava Flow shaped the landscape, leaving behind a mesmerizing tapestry of rock formations and unique ecosystems. Its geological wonders and cultural significance continue to inspire awe and fascination among visitors.

Geological Formation: Parkdale Lava Flow

Parkdale Lava Flow

The Parkdale Lava Flow is a prominent geological feature located in the Cascade Range of Oregon. It was formed approximately 70,000 years ago as a result of a series of volcanic eruptions from Mount Hood.

The lava flow consists primarily of basalt, a type of igneous rock that is characterized by its dark color and fine-grained texture. Basalt is formed when molten rock cools rapidly, resulting in a dense, glassy material. The Parkdale Lava Flow also contains smaller amounts of andesite, a type of igneous rock that is intermediate in composition between basalt and rhyolite.

Age and Extent

The Parkdale Lava Flow is estimated to be between 70,000 and 100,000 years old. It covered an area of approximately 20 square kilometers and flowed for a distance of over 10 kilometers from its source at Mount Hood.

Impact on the Surrounding Landscape

The Parkdale Lava Flow had a significant impact on the surrounding landscape. It blocked the flow of the Hood River, creating a natural dam that formed the present-day Lost Lake. The lava flow also diverted the course of the Sandy River, creating the present-day Sandy Gorge.

Ecological Significance
