  abstract = {{Bladed Terrain on Pluto consists of deposits of massive CH$_{4}$,
which are observed to occur within latitudes 30{\deg} of the equator and
are found almost exclusively at the highest elevations ($\gt$ 2 km above
the mean radius). Our analysis indicates that these deposits of
CH$_{4}$ preferentially precipitate at low latitudes where net
annual solar energy input is lowest. CH$_{4}$ and N$_{2}$
will both precipitate at low elevations. However, since there is much
more N$_{2}$ in the atmosphere than CH$_{4}$, the
N$_{2}$ ice will dominate at these low elevations. At high
elevations the atmosphere is too warm for N$_{2}$ to precipitate
so only CH$_{4}$ can do so. We conclude that following the time of
massive CH$_{4}$ emplacement; there have been sufficient
excursions in Pluto's climate to partially erode these deposits via
sublimation into the blades we see today. Blades composed of massive
CH$_{4}$ ice implies that the mechanical behavior of
CH$_{4}$ can support at least several hundred meters of relief at
Pluto surface conditions. Bladed Terrain deposits may be widespread in
the low latitudes of the poorly seen sub-Charon hemisphere, based on
spectral observations. If these locations are indeed Bladed Terrain
deposits, they may mark heretofore unrecognized regions of high
