In my March 23rd trip report, I mentioned hearing barks every once in a while as I hiked around in the daylight hours. I managed to isolate one of those barks, actually a double bark, from my recordings and wanted to share it as an example of what I kept hearing. The weird thing about these barks is how indistinct they were, I could never get a fix on where they originated from. This example was captured a short time after 10:00 PM:
