[visited 8/1/12] Without a GPS and with blanket mist, I found this by educated luck, basically heading downhill in the right direction from the main barrow. Its a fairly small enclosure, presumably designed to keep cattle penned in as the high land immediately next to it would have made defensive use very difficult. The banks that are left look to be in good condition, though I didn’t walk the whole thing as I was getting rushed for time by this point.
Access is the same as the rest of Eldon Hill.
