In this paper we report numerical simulations of the dynamical evolution of the region a >50 AU. We found that some dynamical effects such as high-order secular resonances with the rate of precession of Neptune's node of the form with k=4,5,... or combined mean motion resonances with Uranus and Neptune of the form may increase the area of a very thin primordial disk in this region by a factor of up to 2 after 4.5 Gy of evolution.
