Marcus Landslide Day Hike
when Saturday, March 16, 2019
where McDowell Sonoran Preserve, Scottsdale
the hike     Did you ever wonder what a mountain would look like 500,000 years after half of it fell down? If so, this is the hike for you. Two ASU graduate students discovered this formation in 2002. Now it’s the highlight of an interpretive trail the northern part of the Scottsdale Sonoran Preserve.
    There are about 20 interpretive signs along the way, which explain a little about the geology of the area and the various reasons why this massive movement of earth may have occurred. The trail is a lollipop formation, out to the landslide, a loop up on top of the landslide, and back on the same trail. Along the way we’ll see an collection of unusual rock formations.
    There are toilets at the trailhead but no drinking water.
