The official Universal Orlando twitter posted a better quality image of the Shadow Creek facade last night. The picture is located here
In this picture, you can clearly see that this facade is for Sprung Tent 2, which if I recall correctly is the rumored military house. Shadow Creek could be a military base or outpost, the emblem in the center has the Greek letters Alpha and Omega. Emblems such as this are common, not just in colleges and fraternities, but in specific military platoons or battalions.
Hopefully I'm not to off base with my assertions and I've shed some light on the Shadow Creek issue.
