A hole that, according to Jude McHugh a spokeswoman with the Willamette National Forest, has been there as long as anyone can remember, during the winter opened up under Oregon’s Lost Lake and the lake started running down the hole.
Apparently, the area’s volcanic landscape is to blame for the lake’s rapid drainage. Geologists believe a lava tube beneath the lake formed when flowing lava hardened near the surface and flowed downwards. As the eruption cooled, the hardened pips emptied, leaving behind tubes in the form of vast tunnels.
Other lakes in the area have similar lava tube drain holes, Fish Lake, for example, which is only a few miles from Lost Lake, according to The Bulletin.
Researchers are mostly bewildered as to where the water is going. McHugh claims it may seep into the porous subsurface underground, refilling the aquifer that feeds springs on the Cascades, although that has not been confirmed.
According to the sourcelink, local people have found some unusual things in the lake, car parts, engines and such. McHugh believes these are attempts to try to ‘plug the leak’, but warns this may simply lead to flooding of the local area.
‘If anyone was ever successful at plugging it, which we’re not sure they could do, it would just result in the lake flooding, and the road. It’s an important part of how the road was designed,’ she said.
