Well, it has been two nights in a row now that we have had loud rumbling noises here in the Canyon.
YES, for me it is very scary and I remain sleepless! It has to be rock slides... as in the past weekend we had nearly 48 hours worth of moisture! I plan to do some hiking this weekend and will investigate. At first I felt like I was only one of two locals who heard and felt it but it continued last night and now others are commenting.
We had a terrible earthquake back in 91 or 92 and I will try to hike up to the center of it ....this weekend as it is only about 2 miles from me.
Nothing like an adventure for this "zion girl"!
