This memorial containing pieces of wreckage is located just east of Lake Tahoe, Nevada & is dedicated to the 85 lives lost on board Paradise Airlines Flight 901A.  From Wikipedia, on March 1, 1964, the plane was making a scheduled passenger flight from San Jose, California to South Lake Tahoe, California when it crashed on the summit ridge of Genoa Peak, Nevada.  An investigation concluded that the primary cause of the accident was the pilot's decision to attempt a visual landing approach in adverse weather. After aborting the landing attempt, the pilot lost awareness of his location as he flew below the minimum safe altitude in mountainous terrain. He likely tried to fly through a low mountain pass in an attempt to divert to the airport in Reno, Nevada, and crashed into the left shoulder of the pass. The wreckage spanned roughly 900 feet & left no survivors.  Had it been a mere 100 feet more to the right at the altitude it was flying, the plane would have cleared the ridge.  At the time, it was the second-worst single-plane crash in United States history, and remains the worst accident involving the Lockheed L-049 Constellation.

The airline involved, Paradise Airlines, was a two-year-old company that operated discount excursion flights from the San Francisco Bay Area to Lake Tahoe. After the accident, investigators from the Federal Aviation Administration (FAA) uncovered multiple safety violations by the company and grounded all of its flights. After an unsuccessful appeal by the company, the FAA revoked its operating certificate and Paradise Airlines permanently shut down.

A somber location, many visitors & family come to pay their respects.  Most visitors arrive via an off-highway vehicle or vehicle w/ high clearance as the approach is narrow & rugged.  A swing on the nearby tree provides a nice relaxing vantage point of Lake Tahoe in the distance.
