The newest course at PGA WESTŪ is in a plain -- a seabed 40-feet below sea level -- that's surrounded by an immense crescent of terra-cotta mountains. The course teems with purple, white and yellow wildflowers. The mix of tall and short native grasses produce different shades of green running almost to silver, and the trees -- mesquite, paloverde and acacia -- are native to the low desert and are visually arresting.
