Porkchop Geyser's name derives from its pork chop-shaped sinter mound. Measuring around 2 feet in diameter, the geyser was once a tranquil hot spring until 1971 when it began erupting intermittently. In 1989, it experienced a violent hydrothermal explosion, scattering debris over 200 feet away and significantly altering its appearance. In that year, a visitor named David Kirwan died after attempting to rescue his friend's dog from the hot spring.

Congress Pool, named in 1891 during the Fifth International Geological Congress, is a prominent geothermal feature in Yellowstone. Its activity fluctuates from a steaming, dry vent to a boiling, murky hot spring, and occasionally an overflowing blue pool. The pool was one of the first to be discovered containing Sulfolobus, a thermophile that thrives in hot, acidic conditions by converting hydrogen sulfide into sulfuric acid. Additionally, new viruses have been identified using Sulfolobus as their host, highlighting the pool's importance in studying extremophiles and microbial life.
