   Interesting ideas Casey.

   But I don't have a clue to this one.

   Just wanted to tell ya that I have fond memories of Portland! Jez keep telling everyone it's constantly raining, and therefore to stay in California!

   Maybe the stone is pressed in with a tool in the shape of the foot print , as in pressed patterns that make concrete look like brick, cobble stone ,etc.

   *Casey;I'll add my 2 cents...perhaps the stones are added after the surface is floated- like it will be an exposed aggregate-just at the foot prints (or perhaps all of it?) The surface is then worked to submerge the aggregate. In the areas where there will be foot prints, some "magic" material is placed to prevent curing. Once the surface has set, the foot prints are washed out.Die-cut footprints of this material (felt impregnated with ?) would simply be placed on the curface.I don't know, I'm rambling.......Adam

   *Casey, This does sound interesting;the type of job which a finisher can take pride in. A bit touchy, but enjoyable. The mix design would be important;6 bag, 6% air max, addional aggregate (300-400 lbs/yard). A footprint "stamp"could be used, having been coated with a "paste" retarder(typically used for exposing vertical surfaces). The slab would be broomed first,preferaably with a soft horsehair broom,leaving the surface soft enough to take a 1/8" impression. Timing is really an on-site judgement call. I'm not sure if each stamp could be used more than once,that isif removing it after making the impression would leave behind enough residue or film of retader to wash/expose the stone later.Once again,on site timing. You might want to try contacting Colorado Hardscapes on the web. They are very accomplished and always innovative. Ciao, Rick

   One of the small parks in downtown Portland has a decorative detail in their sidewalk that I wouldn't mind replicating if I can figure out how. It consists of what looks like animal tracks (deer, elk, bear, raccoon, cougar, etc. as well as some birds) in the concrete. The main sidewalk surface has a traditional brushed surface with each "track" being inset about 1/8" with small (about 1/2" to 1") river rock in the bottom. I assume one could use something like a cookie cutter in the shape of each paw print and then shove scoop out some of the mud and replace it with small rocks, then upon removing the "cookie cutter" mold, carefully sculpt the edges of the paw print so it looks like the top 1/8" of the concrete was simply lifted out of the sidewalk. Sounds like it could be a lot of work and require a lot of molds (left and right for each animal at minimum). Any idea on the easiest way to do this? How stiff should one let the pour set up before working on it with the "cookie cutters" so that one could tamp in the rocks without messing up the surrounding area?
