The initial conditions for star formation in our Galaxy are difficult to establish. We seek to address this problem by imaging an archetypal region where new clouds are forming, around the periphery of the expanding supernova remnant W4. A 2-by-2 degree map with MIPS at 24 microns will reveal the structure of these clouds and their cores at unprecedented detail, with uniform imaging of scales of 0.1 up to 10 pc. A clump mass function will be constructed using temperature constraints from longer-wavelength data. This information on mass distribution and structure will then be compared to the results of our simulations of supernova impacts on the interstellar medium. Hence, the dominant forces on pre-star-forming clouds can be deduced.
