MORNINGSIDE HEIGHTS?Columbia University's Manhattanville will one day be filled with expensive buildings for people to stuff their heads full of knowledge, but right now, it's just a big hole in the ground. A tipster sent along the above photo, showing the construction site from the Riverside Drive Viaduct. According to Columbia's website, current work includes demolition of some buildings along 130th and 131st Streets, the installation of slurry walls and foundations, and installation of a new sewer system.

CHELSEA?The High Line may be New York's least confusing park to navigate, but nevertheless, it now has an app guide. Called "On the High Line," the app is based on an illustrated guidebook of the same name. It features seven videos, more than 80 photographs, information on kids' activities, and maps of the park, surrounding neighborhoods, and notable architecture. There's also something that lets you make your own High Line postcard. It costs $3.99. [CurbedWire Inbox; official]
