I've just added Elk Creek and West Fork Elk Creek to the map, based on a hike (https://www.oregon.gov/ODF/Documents/Recreation/Kings_Mtn_Elk_Mtn_Trail_v2009.pdf).

However, I'm a bit confused here. 
Does anybody understand why the road going Northwest from here is called 'Elk Creek Road' and the road going northeast 'West Fork Elk Creek Road' while is located on the east side. Additionally, the forks of the Elk Creek coming from Northwest to here is called West Fork Elk Creek and the fork coming from east is called Elk Creek (the main fork). Thus the creek naming contradicts the road naming.

Does anybody have an explanation for this?

This matches with the given of USGS Topo map.
