Hi Beth,
Like any good Dutch Hunter, I looked into the Bavaspi earthquake......years ago. Newspaper articles of that era tended to get a little flowery and often exaggerated.
I have no doubt that the earthquake did damage to the mountains, as well as the area between the Superstitions and Bavaspi. That being said, I don't believe it appreciably changed the topography of the range. Cliff faces probably calved off in many cases, but that would not be considered a major change to the mountains.
I believe any earthquake sever enough to change the topography of the Superstition Mountains, would shake most of the balanced rocks to the ground.
Here is what Tom Kollenborn wrote about the event:

Here are other articles from the Internet:

The intensity level was considered "Very light" to "Light" in the area of the Superstitions. Those who were there, might have felt otherwise.

There are many, many places in the Superstitions where good sized slides have taken place over the centuries. The overall topography has remained unchanged.
As I was not there, I could be totally wrong.
Take care,
Joe
