The first beautiful dune in Mullamullang, foot prints of the first excited explorers as they dashed into the amazing new cave, not believing what they saw. Walked around this dune on 5th Jan 1966 with 43lb pack, which Mary carried for me to the entrance before kissing goodbye and heading off to supply the camp. Wednesday...05-01-66 Notes from my 1966 diary, entered here, 07-01-2017 Dick and I headed in at 2:30pm, passing few people on their way out. Got to the camp at about 7pm, made bed of rocks near Rick's, then Dick and I to the end of Mullamullang. Bruce and Glenn came too. My feet were getting sore! Photos of us at the end and then back to the Grotto. Photos of gypsum and then swimming in the lake. Camp, another swim, and to bed. Tea in bed & talked to Rick and Dick. Great to be there with them, gave them fresh water. They had record player going as we were lulled to sleep about 12:30....
