Observations during the spring and fall 2017 field visits found <br /> little remaining evidence of this crack. This lack of observed evidence of the crack was again <br /> confirmed during the spring and fall 2018 field visits. <br /> Subsidence features had previously been observed at several locations along this traverse between <br /> MVB E6-10 and MVB E6-11 as longwall mining had passed beneath this area between the fall of <br /> 831-032.900 Wright Water Engineers, Inc.
