A mystery photo. Pure saltwater cordgrass is on the left;
pure salt hay is on the right. One thing is that the two dominant
grasses don't mix, but even more mind-bogging is the
presence of this bare line separating
the two! If this is a trail, then who in the
world would position it directly along the demarcation
line between the grasses? Does anyone have a clue?
