PORTLAND — Spring break is coming back to the Oregon Museum of Science and Industry, and the museum pulling out a crowd pleaser to welcome people back.

The family-friendly science museum in Southeast Portland said “Dinosaurs Revealed” will be its featured exhibit this spring.

OMSI also is planning an exhibit about the vaccines against COVID-19, museum spokesperson John Farmer said, but it wanted to provide families an escape from the pandemic.

“Let’s just have some fun for crying out loud,” Farmer said. “And what could be more fun than giant dinosaurs roaring through the halls of OMSI?”

The “Dinosaurs Revealed” exhibit will debut to the general public on March 20, opening a day earlier for museum members. It will be on view through Sept. 6 — as long as the museum stays open this year.

The museum shut its doors March 14, 2020, becoming one of the first large attractions in Oregon to close as COVID-19 began circulating throughout the region. It reopened in June and remained open until November, when state officials once again issued tighter lockdowns on public gatherings.

OMSI on Feb. 18 partially reopened its Natural Science Hall, Kendall Planetarium presentations and the USS Blueback Submarine to a limited number of guests at a time. The museum’s other attractions have so far remained closed this winter, though Farmer said the theater could reopen soon.

Day camps will continue for summer 2021, and are already over 75% full, OMSI said. All overnight camps have been canceled for the year.

Several other Portland area museums remain closed as spring approaches, though at least one other destination plans to reopen. The Oregon Historical Society announced it will reopen March 6, but will only be open for limited hours on the weekends. However, the museum will host special hours for Oregon schools’ spring break, opening from noon to 5 p.m. Tuesday-Sunday, March 23-28.

As per state regulations, OMSI will limit the number of people allowed into the museum at a time. Multnomah County is in the state’s “high risk” category, which means museums can only operate at 25% capacity. If the county is reduced to “moderate” or “lower risk,” museums will be allowed to operate at 50% capacity.

The museum will manage crowds by selling timed-entry tickets online in advance. Tickets are available at tickets.omsi.edu.

Farmer said the high risk protocol means about 120 people per hour would be allowed into the museum, making for an intimate experience in the 7,000-square-foot exhibit hall that will house “Dinosaurs Revealed.”

OMSI will require all visitors and staff to wear face masks and will ask visitors from different parties to maintain 6 feet of distance. Parties visiting the museum together are now limited to no more than six people. Staff will be on hand to enforce the rules and regularly clean all frequently touched surfaces.

The pandemic may have upended the museum’s previous spring break exhibit (“Body Worlds” opened one week before the museum closed last year), but “Dinosaurs Revealed” seems primed to stick around, offering visitors a vintage OMSI experience that never fails to impress.

“The cool thing about this exhibit is it is classic science museum dinosaurs … there’s a triceratops that’s the size of an actual triceratops and a T. rex that’s 20 feet tall,” Farmer said. “It’ll be fun, it’s what we need right now.”
