The Amphitheatre is an iconic outdoor concert venue with a capacity of 22,500, featuring both reserved seating and a lawn area. Since it opened in 1986, it has hosted several concerts and other events, including major music festivals like Lollapalooza and Ozzfest, as well as annual charitable events such as Neil Young's Bridge School Benefit Concerts.
The parking lot where this cache is located, right outside the main entrance to the amphitheatre, will be inaccessible on event days. As a result, I recommend parking in Lot C or Alta Garage, and making the short walk over from there.
