After a near week-long closure, Lanterman's Mill is open to guests once more.

The mill had announced a temporary closure on Friday due to a "serious medical emergency," which was later revealed to be the cardiac arrest of longtime manager, Greg O'Neal. 

Mill Creek MetroParks announced on Monday O'Neal had died as a result of this cardiac arrest.

The mill is open Tuesday through Sunday from 10:00 a.m. to 5:00 p.m. and closed on Mondays.
