Another comment above says the NSF is contracted to return the site to its natural state and that since the collapse it is safer to enter the structure and begin removal.
Hopefully they follow through. Sometimes people find sneaky ways to get out of their contractual obligations. Especially in cleanup jobs such as this where the primary damage is to the land. It can be difficult to find someone with both the power and interest to enforce such contracts.
Well it is operated by the National Science Foundation. So we can hope that they have an interest in preserving the forest floor below.
But then again, with budget cuts and the decreasing budgets that science and climate organizations have been getting from the government lately, this is entirely possible.
