Latest News

From the Desk of the Executive Director – IDSDC Construction

by | Jun 10, 2024

For those of you following the International Dark Sky Discovery Center, you’ll be happy to know that construction has begun. This will impact the River of Time over the next couple of years until the center is completed.

We’ll provide access updates via the newsletter, email and Facebook postings, so be sure to follow in order to stay on top of the latest changes. The IDSDC communications and project management staff have assured us that there will be minimal disruption to River of Time operations.

Effective immediately, access to our loading dock (back) door will be closed off for several weeks so we will not be accepting Holiday Mart donations during this time. To coordinate Holiday Mart drop offs at our storage location, please contact Barb Gierer at

As soon as the construction equipment begins to arrive, the south parking lot, closest to the River of Time entrance, will be closed until construction is complete, probably at least two years.

Parking will be in the north lot, closest to the Community Center. We haven’t been advised of a firm start date, but anticipate sometime in June. As soon as construction fencing goes up, parking will be diverted.

You’ll also notice fencing and projects going on in Centennial Circle. These are Town of Fountain Hills projects and should be completed by the end of June and don’t affect River of Time operations. Our Milestone Art Tours will return in October.

Please be assured that the River of Time staff and Board of Directors are working to make sure that the impact of construction on our operations is minimal. Please contact us if you have any concerns at

Cherie Koss, 
Executive Director  – River of Time Museum & Exploration Center
