In our first week of caching as brand new cachers, Mini and I hid a cache near here, the former "The Diamond Mine" cache, which got muggled. Once it was muggled, I decided to archive it instead of replacing it for a few reasons, those being that 1) In it's very short life, my cache got compromised by muggles a few times before it completely went missing, 2) User logs on my cache told me that another cache once held that spot and I decided that between mine being muggled and tampered with several times in the span of a month and the last one being possibly muggled, this is a dangerous cache zone for muggle activity, and probably most importantly, 3) I looked into the "cache history" of the spot and discovered that the former cache there once belonged to a series and I felt bad for unintentionally "stealing" the spot.
All of that aside, I really wanted to hide a cache near here because I have fond memories of riding my bike though these corridors with my brother when I was very young. I used to love looking at the hydro towers and imagining them as giant statues of warriors without actually knowing what they were (my awesome 4 year old imagination 
). Anyway it was fun and I never actually walked through these corridors again until recently and it made me feel warm and fuzzy, although that could be the EMFs (kidding). We found this spot which is a fair enough distance enough away from the old spot and still allows us to hide a cache nearby and in the Hydro Corridor so we bring to you the "Warrior Towers - Gatineau Hydro Corridor Cache".
There is parking across the street at the corridor on the east side of Pharmacy.
Note: I have a micro 1" container in the tree, this is not the cache. I placed it but changed the cache with a bigger and better one. I couldn't find the tiny one to remove it in the dark when I went to swap it out so in the mean time, please ignore this tiny one and go for the larger one.
