Abstract: 

The New Horizons flyby of the Pluto revealed a planetary surface showcasing an active low-temperature physics laboratory.  Detailed analysis of the encounter hemisphere reveals surface features consistent with both present and past glaciation by N2 ice.  In this talk I will present a walk through of the images considered indicative of glacial activity followed by a discussion of the various issues that are raised by the implications of N2 ice glaciation. I will conclude with a survey of some of our preliminary attempts at modeling the processes therein and some of our near future goals toward understanding this fascinating system.
