Where the Rocky Mountains are relatively new mountains, mountain building does not affect all areas equally. The stress of subducting plates being pushed under overlying plates, or compression of land being crinkled as it is pushed horizontally, being distributed to the weaker parts of the mountain range. Thus US states lying in old rock, which gives evidence of not having succumbed in the recent past, is a good indication of safety during the coming changes. Salt Flats are such places, but are subject without protection to the hurricane force winds that will rip all parts of the globe. Where rock surrounding valleys is smooth, without rough edges indicating recent tears, these valleys may be considered safe in Utah. Existing mountain ranges have drainage patterns that give an indication of where water from temporary deluges will go. Dry creeks and river beds, gullies with water wash marks, and places where they occasional waterways join with draining rivers. Where water is trapped inland by hardened rock, temporary lakes may form, but due to the overall dryness of the area and high altitude, subject to steady winds, these will not last for long.
