In a large bowl combine cream cheese, sour cream, mayonnaise, New Mexico chili powder, ground cumin, pepper, garlic powder. Stir with a spoon until well mixed. Add 3/4 of the bacon, 1 cup Colby Jack cheese, 1 cup pepperjack cheese, and drained jalapenos.
Spread into a 10" cast iron skillet (or (2) 5" skillets for the perfect party plate). Top with the remaining cheese. Bake for 15-20 minutes until the cheese is bubbly.
Sprinkle with reserved bacon and parsley. Serve with a bag of crackers or your favorite dippers!
