Presently, an American RIAA-certified Gold record is a single or album that has sold 500,000 units (records, tapes or compact discs). The award was launched in 1958; originally, the requirement for a Gold single was one million units sold and a Gold album represented $1 million in sales (at wholesale value, around a third of the list price). In 1975, the additional requirement of 500,000 units sold was added for Gold albums. Reflecting growth in record sales, the Platinum award was added in 1976 for albums selling one million units, and singles selling two million units. The Multi-Platinum award was introduced in 1984, signifying multiple Platinum levels of albums and singles. In 1989, the sales thresholds for singles were reduced to 500,000 for Gold and 1,000,000 for Platinum, reflecting a decrease in sales of singles. In 1992, RIAA began counting each disc in a multi-disc set as one unit toward certification. Reflecting additional growth in music sales, the Diamond award was instituted in 1999 for albums or singles selling ten million units. Because of these changes in criteria, the sales level associated with a particular award depends on when the award was made.

Crater Lake (Klamath: giiwas) is a caldera lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep caldera that was formed around 7,700 ( 150) years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth.
