As those flowers have four petals, and all of the phloxes have five petals, I am pretty sure that you are looking at a massive patch of Dame's Rocket, a non-native-to-America member of the mustard family. They can range in color from white to pale blue, very much like the wild phlox known as Sweet William, to lilac to pink, to deeper blues to violet, sometimes all in the same patch of them.
The bad news is that they are often considered invasive competitors to whatever native flora that should be growing there. The good news is that means you can pick as many of them as you want -- if you have permission from the landowner -- since picking them while they are in flower prevents them from going to seed and dropping thousands of seeds per plant! They are known for their fragrance, too, which probably explains why pioneers brought the seeds from the Old Country.
