Squeezed? There are all natural gear. God squeezed them together. I cleaned out the middle crack in 2005 and neve had the balls to lead it as it was. Jim told me it used to have two pins it it. I thought it went at about 10.c or so if you stayed in the crack/seem. I got ahold of Bob McGowen and he told me I could replace the pins with pins or bolts. I never did....due to the wrath that might ensue from those who think they own the rock. Even though I would be within my unwritten right to to so, since I got the FA's permission to do so. An't gonna happen now. I have children.
