Itching for a terrain park open

I just came back from Crested Butte for the weekend and to my surprise when I arrived at CB, they already had a 3 small jumps, 2 boxes, and a tube already open to ride in their smaller terrain park.

I'm still new to park so it was amazing to get some early jumps in, especially considering due to the location of CB the park (and resort) feels practically empty for more consistent park laps. When do terrain parks typically open for the I70 resorts?

Edit: From what I can gather, it seems like this is just a Vail resorts issue 😮‍💨
