TWENTYNINE PALMS (CBSLA) — Joshua Tree National Park was reopened Monday for the first time since the end of 35-day government shutdown – but it may take hundreds of years to return to its former glory.

Parts of the nearly 800,000-acre national park remained open during the shutdown that started on Dec. 22, and ended just last Friday. But eventually it had to be shut down after reports of overflowing toilets and trash throughout the park.

In the absence of park rangers who maintained order, off-roaders plowed down some new trails and destroyed several trees — which can survive for hundreds of years — during the shutdown. People also camped in areas that are normally off-limits, causing even more damage to the pristine desert wilderness.
