A park official says all reservation key maps must be electronically scanned before being sent to visitors.
In a press conference Friday, Mark Siegel said that all reservation maps must also be available online.
He said he believes the online system will be effective in identifying key locations for reservations.
“We don’t want to be on the receiving end of some disgruntled folks who want to send the keys back and say, ‘Oh, you can’t have those,'” Siegel told ABC News.
“You have to do it online, and that’s what we’re doing.”
Officials said they plan to use the digital map to help visitors find out more about the park.
The agency said they will also be conducting a public outreach campaign to encourage visitors to register for reservations and to help ensure there are enough reservation holders.
The parks chief said the agency will begin posting online reservations to help inform visitors about where to go next.
