The above-titled paper by Barnes et al. is being published online today in Geophysical Research Letters.

Jason, I can't access the article right now... Is this the same bright spot as here:

also, I would love to hear some general things about Titan's geology in layman's terms. My limited knowledge about Titan only starts above the tropopause... Can you point me to some good reference or paper? The only thing i've read is Ralph Lorentz's book...

No, that's Hotei Arcus. The study area can be seen in this ISS image:

And in this VIMS mosaic (the bright region at lower right, in SW Xanadu):

Now this paper describes a possible cryovolcanic flow, identified in VIMS and ISS data, in the western portion of Tui Regio. I have attached PIA06192 with the flows outlined in the paper highlighted. There are outlined based on their unique spectral signature compared to the surrounding terrain in southwestern Xanadu, and by their appearance in higher resolution ISS data from Tb (PIA06192 is from T3 last February). These features are identified as cryoflows based on their lobate structure, size (a landslide of this magnitude would require an altitude difference of 3km to for a deposit), and non-radiality (so it isn't ejecta from an impact crater). We also argue that "bluish" terrain in the VIMS data surrounding western Tui Regio is due an airfall deposit from this volcano. We argue that the ISS data suggests that the morphology of the flow is influence by pre-existing local topography, particularly a 60 km wide circular feature northwest of the flow source that maybe an impact crater.
