An advantage of being in a bowl with hills all around is that there’s less background noise. Those hills, which would probably be called levees if there was water on the other side, block out a noticeable amount of AM background signals. This is evident on one of our Part 15 frequencies, 1550 KHz, when we ride the car up and over the hill we suddenly get a station near Branson, MO. Down in the bowl this signal is only heard during the “critical hours,” when the sun is first rising or setting at dusk.
