The very lack of information is interesting, because, for example, the Valley of Siddim is specifically glossed in the OT as being now the Dead Sea; the landscape had changed, but the Israelites knew their geography. The OT account of the wandering between Mt Horeb and Mt Sinai implies that they are one and the same place, but the nomadic lifestyle the Israelites led took them back and forth with flocks. One destination was on one side of the mountain, the other end of the cycle was on the other side of the mountain. Each face had a different name. IMHO, the real mountain has a double peak, and pronounced, basically impassible ridgelines coming out of it, cradling two separate valleys that were worthwhile places to sojourn, but necessitating a long trip along a very specific route, “c”-shaped.
long journey around a mountain, so they gave it 2 names.. heh
