I will refer you to the following link Geologic maps of the San Juan ... Read the photo caption and the short text. You will note the use of the term San Luis Caldera.
The San Luis Caldera Complex is not in the San Luis Valley (where US 285 runs) but rather centered around San Luis Peak north of Creede. Great examples of the volcanics are exposed north of Creede. The San Luis Valley is a rotated fault block valley in many ways similar to the Basin and Range type of geology of Nevada and Western Utah which explains the flatness of the valley.
At one point many years ago I spent some time mapping those volcanics just off of CO 114 and later studied the San Luis Valley as an analogue for some of the geology I mapped in NV.
