My wife and I can be found walking in our neighborhood, two or three times per week, since the walking track at Park High School's Activity Center closed, due to Covid. It has yet to reopened. Some of our walks, we are amazed with our neighborhood finds.
A couple blocks down and around the corner from my home, one of the neighbors has created this ginormous, DIY snow castle. We first saw this structure when they were working on the third layer. I can confirm there are plywood boards used in the snow castle to help with support. The fourth layer was new to us this week. We unfortunately did not dress warm enough for the 13 degree temperature, so it was a quick walk.
I would estimate this is 40-45 feet tall.
