Tuesday, August 4, 2015, Boulder County Dispatch received a call from a couple
who was walking at Stearns Lake, part of the Boulder County Parks and Open
Space system, in reference to a possible hand grenade they found along the
shore line. Stearns Lake is located at
2100 S. 104th Street in unincorporated Boulder County.
While taking an evening walk around the lake, Rachel Wine
and Anthony Perkins decided to walk in an area where part of the lake had
receded. As they were walking in this
area, one of them unknowingly stepped on an unexploded hand grenade. As they looked more closely at the object
that had been stepped upon, they realized it appeared to be a grenade. Luckily, due to the time of day and location
of the park, they were the only people present in the area. They moved away from the area and called 911.
Deputies from the Boulder County Sheriff’s Office responded
and determined this was in fact an unexploded hand grenade, and contacted the
Boulder County Regional Bomb Squad. Bomb
Squad members determined the grenade was live, and likely from the World War II
era. Because of rust which had developed
on its surface from having been at the bottom of the lake for an unknown period
of time, the decision was made to use explosives to detonate the device on
Also present were members of the Louisville Fire Protection
The detonation was successful, and no property damage or
injuries occurred. It is unknown when
the hand grenade was thrown into the lake, or who was responsible to doing so.
County Sheriff’s Office case number for this incident is 15-4383.
