Papago Park Geology Overview
Transcript of Papago Park Geology Overview
A Geological Overview
[kuhn-glom-er-it] noun, Geology - A rock consisting of pebbles or the like, embedded in a finer cementing material; consolidated gravel.
Billions of years ago, this region was considered a hot bed for diverse geological activity.
Papago Park's geology dates back 30 million years ago
Once a high mountain range standing as high as 7000 ft and made of rock species that no longer exist here.
Much of that original rock formation has been up lifted from the region and ended up off the coast of California.
Comparatively Mertopolitan Phoenix is 15 to 30 million years old and considered amongst the youngest geological formations in the state.
Other Rock formations include granite coming from the Camelback mountain range.
The geological formations existing today within the Papago Park boundaries are mostly made of Red Beds also referred to as Tempe Beds that are red rock.
Most of the formation from remaining geology was created by:
• Slow ground movement
• Not more violent activity such as earthquakes or volcanic activity.
Some of the oldest geology within Arizona, such as the mountains of both Sadona and Tucson date back approximately 27 billion years ago.
Papago Park's neighboring "A Mountain" was partially formed by volcanic activity
These "Hole formations" are still being formed by what is referred to as a modern weathering phenomenon.
[ yahr -dahng ] noun, Geology - A keel shaped crest or ridge of rock formed by the action of the wind, usually parallel to the prevailing wind direction.
The texture in a variety of buttes are created from Yardang
Yardang occurs through the combination of
• Soft rock's steep vertical formation
• Micro climates
• Wind currents
• Hot sun
• Coarse grain rock
Thoughtout Papago Park, the 2 major types of rock stratta are
[brech-ee-uh] noun, Geology - Rock composed of angular fragments of older rocks melded together.
South Mountain shows evidence of earthquake activity as part of its formation.
Billions of years ago, long before this region became the desert it is today, this region was considered a hot bed for diverse geological activity.
Within this region, Papago Park sits within a slightly unique pocket of activity from its surrounding geological neighbors.
