@RebelCMX, you reminded me the 'Bhir Kate'.  I used to go once in a while through 'Bhir Kate' but that's not in Myagdi or Taplejung though :).  The trail was cut in angle (the slope was vertical or may be also reverse). I used to run through that trail to show my 'bravery' among my friends. Now I can imagine the risk and my stupidity at that time.
I havent watched the above video (will do later if possible) but let's see your picture.
