In July of 2015 the New Horizons spacecraft flew through the Pluto system, completing humanity's reconnaissance of the classical planets. Pluto turned out to be a world of remarkable geologic diversity, and its terrains display a range of ages, suggesting geologic activity of various forms has persisted for much of Pluto's history. Pluto's atmosphere was found to be more compact, and with lower escape rates, than previously predicted. Hi-phase images looking back at Pluto's atmosphere led to the discovery of numerous haze layers. Pluto's large moon Charon appears to have had an early large cyrovolcanic resurfacing episode along with large-scale tectonism. I will summarize what we have learned so far about these complex worlds and also discuss some of the unique geologic features seen on Pluto and Charon, including putative cryovolcanos.
