The stolen cross memorial in California's Mojave Desert was anonymously replaced this week with a replica.
According to Mojave National Preserve spokeswoman Linda Slater, a maintenance worker found the white, painted replica bolted to a concrete pad on Sunrise Rock Thursday.
"Technically, it's illegal," Slater said. "The Park Service has regulations about people putting up memorials. You can't just go to a park and put a memorial to a family member."
Officials have removed the replica cross.
The original seven-foot cross honoring America's veterans was stolen by vandals in early May after the Supreme Court ruled the monument could remain on federal land.
Several veteran groups remain outraged by the theft of the original monument, which served as a memorial to World War I veterans for 76 years. They have offered $125,000 in rewards for information leading to an arrest.
"We've had offers from all over the United States from people wanting to help" replace the cross, Wanda Sandoz said. "One gentleman wanted to make a granite cross, 10-foot, and another a redwood. And they would be beautiful ... but we really want what the veterans chose."
