A container for holding a document at a well site comprises a housing having a cavity into which the document can be received. The cavity can be substantially fluid-tightly sealed by a lid appropriately connected to the housing. The housing has a side in which a window is disposed to enable one to determine whether anything is inside the cavity without having to open the lid. The housing has pairs of holes defined therein so that the housing can be connected to well site structures which are disposed at different angles to the ground.
