There are numerous quilt blocks that are named for cities, states and other places. Here is just the start of the list in a variety of quilt block sizes.
Chisholm Trail Variation
Free Quilt Block Pattern
This four patch quilt block is a slight variation of the Chisholm Trail quilt block. By a simple different arrangement of the light, dark and medium values of the fabrics it appears to be a totally different block. The block features simple patchwork, using only squares and half square triangles.
The sample quilt layouts show two very different quilts. One quilt uses a side by side block setting, while the second quilt sets the quilt blocks on point. Both quilts use sashing to separate the blocks, with very different results.
