Residents of the Kuiper Belt are referred to as Kuiper Belt Objects (KBOs). KBOs and the Kuiper Belt are remnants from the era of planet formation in our Solar System, 4.5~billion years ago. The location of a change in slope at the faint end of the KBO magnitude distribution can be used as a proxy measurement for the dynamical age of the outer Solar System, and three recent studies have found significantly different values, implying very different histories for the outer Solar System We propose here an Archive project to harvest 50--100 R<27 KBOs from a number of existing ACS/WFC datasets. We will derive the KBO magnitude distribution and magnitude of change in slope (if any) from a large number of faint KBOs. We will measure the number and magnitude distributions of KBOs as functions of latitude, longitude, and KBO inclination. Dynamically hot and cold KBO populations may have different magnitude distributions, alluding to differing evolutionary histories. With these results we will constrain the dynamical history of the outer Solar System.
