Pleasant singletrack through the woods. Never too steep.
North half opened July 2014.
South half opened September 2019. Connection to Blue Blossom now easy to do without riding on the highway.
In 2019, the eastern most portion of the old Steam Donkey Trail was decommissioned, and the lowest portion of the 2014 Oljon trail was renamed to Steam Donkey.
