The "structure" in the photo you posted was investigated and found to be a geologic formation. Like the "face" on Mars or the Giant's Staircase in Ireland geology can be mistaken for man (or giant) made features of the landscape. Continuing to promote them when they've been reliably explained does the argument for Biblical veracity no favors.
Never understood why so many people expect the Ark to still be visible today......nothing in Scripture says so, and there’s little chance that any of it survived the centuries.
